Hi, you mean pythagoras? d = sqrt( (x1-x2)^2 + (y1 -y2)^2 ) Klaus
Can you please explain what you mean by "...stops working"? Also can you compile the code (unaltered) and run that or does it only work with some pre-compiled version of the program? (Some of the image files have dates that are about 18 months earlier than the source file.) Finally does this work in real hardware? If so then it could be a bug in th
When you say "movable" it is supposed that you mean to scroll the picture either at an horizontal or vertical direction. Although Codevision supports many graphical display chipsets, each one having its own features, the generic option to code that, irrespective to the LCD manufacturer, could be by plotting the same picture at each new update but s
Your attachments don't work. Just because you used the same software and physical setup doesn't mean you should expect the same results. What convergence criteria did you use? Did you specify a seed mesh? What's your final tetrahedron count? The mesh quality has the possibility of drastically altering results.
did you mean that there should be an"yes/no" letters to be shown or an image should be displayed ? you can give more info with some details , like what exactly you want to diaplay and what are the switches labelled to control it.
I know it's probably a bad idea regarding blinding someone. But as opposed to phased array design that would probably mean more expensive. What about spinning a laser and creating a 3D map of the image returned from this spinning laser. I don't even know if it makes sense, if the laser bounces off a non-flat surface, how to account for th
while searching for 0ohm resistor to use at 2.4GHz, I came across a search result like the image below. 119768 Why the word 'jumper' as a value for tolerance? What does this mean? Is it somehow related to 'jumper wire'??
it depends what you mean by'image processing' and 'slow' for image processing applications I would look at DSP systems, e.g. also have a look at
can u explain your question in detail??..what arithmetic and what do u mean by memory issue??
Hello all, I want to work on these subjects: FUZZY image PROCESSING Lp-mean FILTERS WEIGHTED MEDIAN FILTERS MORPHOLOGICAL FILTERING But i don't know from where to begin, for example let's say i'll be starting in fuzzy image processing. I will be doing phd studies from September this year so i would be glad if i got to know (...)
Here by MMS, do you mean multimedia messaging service?? If yes, then you would be neeing a GSM modem..
When we talk about 90nm process, what do we mean by this. Does it mean that minimum channel length (Ldrawn) is 90nm? or Ldrawn is 180nm? In attached image from a journal paper , author is referring to 90nm process, but has mentioned that L=46nm. But previously we knew that according to lambda based rule, minimum channel length must be twice l
Could you describe more specifically what you are doing? I'm not sure what you mean when you say you want to quantise an FFT signal. Any digital signal is quantised, so the input to the FFT and the output are, in general, quantised already. If you want to compress it, I suppose there could be many ways of doing that. Does your compression need t
I guess you mean whorls and ridges? You could compare the slopes of lines (following a line pixel by pixel). Where slope changes, that must be a singular point. However following a line may not always be possible, since you cannot be sure of the quality of the image, and you cannot be sure there won't be gaps in lines. So I think it is easier to
True root mean square
I 've made a boost converter with L6920 As you can see in the image, at LBO pin I've put the cathode of the LED. LBO is an open drain output, which goes low (does that mean it gets grounded???) when the battery voltage goes below the treshold we h
Hi, thanks for help, do you mean that the VCO belongs to PLL block? Another question. TXCO is an oscillator then its frequency is equal to the frequency of VCO? According to the paper, yes. I read it very quickly, but I remember that VCO is considered as part of the PLL block. No, the frequency of VCO varies, a
I'm not quite sure I have understand what you mean. I used file-> export -> image to export the waveforms. I waited a while to be sure the export was completed, but when i opened the .bmp file no waveforms were visible.
Hi I have problem about to write sdram. Column address 256, row address 4096, bank 4. When i get image data from camerasensor, the data size is 2592. But sdram's row address is only 256. The image data coming through 2592 to sdram but when i use full page mode, It's need to "active" what this is mean one more "nop" time. So i (...)
Hello, I need info about the 1- How did the VFBC work ?(Please,If anyone have pdf or link about this subject, send it to me :arrow: ) 2- what is the benefit of the stride ? and what is mean ? I have spartan 3a 3400 and in the demo that came with it there is a VFBC core . and it mentioned in the VSK_top.h //
do help with a matlab code for road extraction using mean shift algorithm from satellite image.
Do you mean that you don't know exact equations in 2D image or how to implement by the matrix programming ? If you want to be professional , you can see the tun of commercial software on internet . 8-O
I am going to guess at about 1 vertical unit. Depends a bit on what you mean by difference. Difference in X? Difference in Y? Vector X/Y difference (assuming X/Y units match). A picture can only provide a guesstimate. An accurate answer would require a table of X/Y values with sufficient entries for the required accuracy, plus a much bette
Dear LvW Can you please elaborate the method. 1) I am not able to understand what you mean by by perform two anlysis , do you mean that i should do two differnt analysis while giving normal/ usual values in the first, giving the changes values in the second analysis, then compare the results of the two?? 2) About the input, Vin=V1+jV1 (90deg lead)
can you provide numerical calculations and code explanation for adaptive fuzzy k means clustering algorithm for image segmentation to my
If InStr(LuminosityValue, "Luminosity Value") > 1 Then Does this mean that when valid data is coming in, the variable called 'LuminosityValue' will contain the text "Luminosity Value"? Will it start at the first character? If so then you need to change the operator to '>0' (or '>=1').
Do you mean for imaging infra-red? If so, what wavelength? Monochrome camera chips will image near infra-red provided they don't have any filters incorporated. Keith - - - Updated - - - Have a look at the monochrome Aptina ones, for
Binary division by primes is going to be annoying. ;-) Divide by 6 has the same issue as divide by 9. And that issue being the division by 3. Divide by 6 is multiplying by 1/6. Lets readily forget about the factor of 2 because that's totally easy. So the problem du jour is dividing by 3. Which is binary multiplication by 0.0101010101010101010
If you mean boot from SPI Does he? If so, hardware configuration load or booting a soft processor image? There are many ways to access a serial flash from an FPGA, the built-in configuration controller is one of them. Why we need to gues when hithesh123 can easily post a clear question? I thought the FPGA would be doing a
what you mean by binary to decimal?
Mr. Smith how do you mean "send me" ? :shock:
Hello Dear experts First of all Please tell me How can I read an image in a Test bench? Also, Is it Possible to read the frames of a video in a Test Bench Continuously, and by this way check the ability of a FPGA design to process an video? What techniques should I use in this kind of Test bench ( I mean test bench for video Processing applicatio
you mean this one?
Hi, Am using libsvm for image classification in matlab. What does training_label_vector exactly mean in "svmtrain" command. What does testing_label_vector and testing_instance_matrix in "svmpredict". After training how to use the results.
Hello! You mean a row of leds that make an image when you spin it? 1. This is an easy question: usually movies give 24 images per second. TV is 25 or 30 depending on the place, so I think a safe bet is around these values or a bit less if you can stand a more "jumpy" image. 2. There is no fixed method. You just have to (...)
You mean in this image?: is a multimeter. Keith.
I got a paper which states regarding SSIM (Structural similarity index measure) as one of the index to measure the image quality. This index lies between 0 and 1 depending on the condition that the structural details of the image is preserved after enhancement. I just wanted to know if structural preservation really mean an improvement in (...)
Hello to the community! I am interested in building a small Synthetic Aperture Radar System able to provide image information up to 1km away, By "small" I mean something lightweight enough that can be used as a sensor unit on a small-sized unmanned aerial vehicle. I would also like it to be cheap meaning no more than 500$. I am aware of (...)
Hi, I have reset all part designator in my schematic and annotate them. But after annotation, some parts (not all) have two designators, one has normal appearance, and the other is in parentheses. You can see one sample on image below. What does these second designators mean? Why do they appear for some components but not for others?
How do I read a bitmap file from external RAM/ROM/Flash memory?? I understand the bitmap file format but how do I access it after storing it in the memory? I mean, when the controller reads data from the memory, how would it detect that a bitmap is stored, there could be other useless/non-bitmap data along with the bitmap image data. Does the
Thank you, that's mean this is very important in digital image processing part.
I think we need more information. Do you mean you want to interpret human gestures? That sounds like a pretty formidable project. You'll need a camera, and some pretty sophisticated image processing to start.
Do you mean how to rotate the image? This means using a formula consisting of sines and cosines. Each pixel must have its x and y value run through the formula, to obtain its new xy position in the new image. Or do you mean how to locate the center whorl? And draw one line through it? So as to indicate (...)
I think you mean shape feature in images then my recommandation is use edge detected algorithm with image enhancement and then some thresholding method will give out shape of the feature in images
OK srinathvarda, I will keep searching around for datasheet, mean while please upload the schematic.
Your image is from proteus (isis), is that what you mean? Alex
Not sure what you mean by the two frequency componets but I assume that it is the image frequencies from the mixer rather than the modulation band width of the signal, which as Keith states all receivers are designed to handle. Consider the two inputs to the mixer as F.LO. The local oscillator, and F.Sig the wanted signal. F.Sig is actually a ba
Hi, You mean from a 9 volt battery as in the image: 61483 If yes have you checked the battery? Is it alive and can feed to the motor?. What type of motor you are using?. Another question (may you take it as STUPID question BUT) is the Battery capable of driving the motor?
did you mean, read two memories, make a comparaison and save the result in a third memory when different to zero? why system verilog? It is not usable to design a chip, but for test/verification.
you mean the equation length longer than one column width?
