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.
Hello, I'm not very knowledgeable about image processing stuff but I'm implementing a method I found in the literature for a project and I found myself with some problems understanding some part of the algorithm related to the application of functionals to transform the image. I am implementing a method known as trace transform for image (...)
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
Dear all, I am implementing an algorithm of image processing over FPGA, actually I have done a good part of it but later I realize I should once confirm it with experienced guys. What I am doing is I am getting 14-bit signal from ADC and I have to do mean subtraction i.e. Taking 500 samples of 14 bit signal and taking mean (scanning (...)
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 Friends, I am very eager to make a propeller display, but I am confuse regarding to some points : 1) What is min. required speed for that ? and how to select actuators for that ? 2) Is there any fixed method for calculation to display anything on it/ or to make a propeller clock ? 3) Can anyone give me some application of it? I mean
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.
i wana simulate mux ic on protious but it gives eror but i couldnt understand what is the meaning of that eror and how can i remove that...please see the attach pic......thnks....any help will be highly appreciated ic n
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?
specifics please.. how have you "converted" the images? is it just append and linearize (eg, in matlab, x_vec = x_mat(:).') ? and what exactly do you mean by "combine"?
Isn't it for 2 rooms only, that is for N=2? I mean, where are the other switches? what about this
Hello all! Some days ago, found this kind of LCD. Can anyone tell me how to connect it? I mean which are the pins for this kind of LCD module? The CI's are PT6608 and PT6607. The pinouts for the CI's are the same with the pinouts for the KS0108 and KS0107 image at URL imageShack Album - 2 images
I have some problem understanding how mean shift segmentation works. The four images below show multi-spectral images from a river. the question is how I can segment a 3*3 pixel area of the image below using mean shift algorithm in the 4d feature space. the image has to be segmented into 2 (...)
Hi; As i understand, if your images are pure artificial images (i mean in red picture there is only red color, no any other color component) then when you read image in Matlab you have an image mxnx3 where 3 is color components r,g,b. The non zero matrix layer gives your color on the image. (...)
i have written the intensity values of an image from matlab to a text file but im not sure abt the order in which the actual pixels of the image are stored in text file. i mean if this is the actual image with the numbers denoting the pixels 1 2 3 4 5 6 7 8 will the corresponding text file store the (...)
