Can we convert 2D image into 3D image through matlab??????? if it is possible then plz give me suitable matlab coding for it. Thanks
hai , I want to know how to divide particular object from an image using matlab. i am expecting your valuable replies
how to find co-occurrence matrix from an image using matlab
Hi all, I am trying to do particle analysis on an image in matlab.I work with nanocrystals of varying sizes and contrast. Basically what I am trying to do is count the number of cells in the image by setting thresholds and make measurements like area, perimeter, radius. The challenge with this work is that the nano crystals change both in (...)
I want to implement pca and dct on an image through matlab. can any body do this ???????thanks will be for him/her.:|
Hi every one can any one help me how can I make Rayleigh fading for image in matlab I have spent long time to find this code but unfortunately I couldn't can any one help me ??
i think it just the same with random bit data,because image or voice must be converted to waveform (bit) before transmit it through RF channel
how to scale/resize image using matlab without changes it original dimension?
Hi; first how can I do a Fourier Transform to this image in matlab fft2 didn't help? Check this
Please use punctuation and capitalisation so I don't need to read your drivel 5 times to figure out what you are trying to write. Also, please describe what you are trying to do in much more detail. You could print out your image, cut t
I'm capturing raw images from an experimental CMOS digital camera. However, this camera doesn't have RGB masks on the CMOS. Instead, the CMOS is monochrome. An instrument with camera lens is fitted infront of the CMOS that has four apertures so that the input image on the CMOS screen is divided into four equal parts (upper left = UL, upper right =
yeah sure.. if u could get me the algorithm by some means... i havent tried changin the luminosity of the images.... and havent seen algorithm for that anywhere!!! :) /Am
Hi everyone! I am user of image processing toolbox of matlab and i have a problem with my project. I want to remove from a face image some hairy spots. Firstly I used a very low pass filter on original image. Also i used a median filter on original image. Hereafter i subtracted the very low pass filter (...)
I'm working with 30-bit TIF image captured by a camera. The camera outputs 10 bits/pixel for each of the three channels. The captured file is saved as 'Test.TIF'. When I try to open it using 'imread' in matlab, I get the following error message: QUOTE ??? C:\matlab701\work\Test.tif: Cannot handle different per-sample values for field (...)
hi frnds, i am doing project in image processing and my work is to find fake currency. presently i segmented the currency image (indian currency). now my work is to find the perfect algorithm for the feature. 1) Optical variable ink( when we tilt the currency,it will cahnge the color into blue from green). for this i can use some c
Hi, I have a .wav file with a signal of a meteorological satellite noaa-14. I need to decode de signal to get an image (in APT format, Automatic Picture Transmission)). I need a matlab program to do this. Anyone out there can help me, please?. Thanks a lot. (Sorry for my English...)

Why imread does not work? What is your image format?
hi all, I'm working in image processing and I need to calculate the fractal coefficients of the image to use them as features to classify the images and I need help getting the matlab m-file that calculate them. if any one has that file or can help me getting the equations and making that file I will be grateful. many (...)
hello friend, I have ten jpeg image in a dir. I want to open all the image in matlab by a single window by the help of "montage". Can anybody help me regarding this. Thanking you, malaya nath
Hi, I'm currently working on a project connected with shape recognition in matlab. I need to generate a CSS (curvature scale space) image and I have some problems with finding inflection points. Do you guys have any ideas on algorythm which will detect inflection points in a binary image? Any help would be great! Cheers!
Are you talking about distance fog, like this? Fog is basically a decrease in contrast or linear blending with a solid color such as blue-gray, but the amount of blending varies according to the distance to the objects in the scene. That's not something you can easily do without depth info.
You can use the matlab function imresize. e.g. B = imresize(A, ); where A is your initial image with size (512*512).
hi, we r tryin to read an image into matlab..... are thr any alternative ways other than imread ().......... we need to convert the image to a data matrix...... its for manipulation in hardware level.......
Firstly u must look matlab's help tool. u will see that imread function. U can use this function to read an image as matrix form. A = imread('cameraman.tif');
Hello dears, I want to match a test image with the template image in matlab, For this task i am using normxcorr2 function for correlation, this function returns an array of correlation between template and test image. This function works fine when template image is a (...)
dear all i have an image and i want to know how i can obtain the pixel value in binary form using matlab? what is the different between the index and pixel value? wait your help for importance regards
how can i get the grey level intensities at each pixel (i,j) in an image I(i,j) using matlab? is there any inbuilt function?
dear all i have an image with size 1500x980 pixel. i load it in variable in matlab and i want to acess or using data bue when i open it this message appear to me 'Cannot display variables with more than 524288 elements.' how can i get this data form this variable? wait your reply for importance regards
Hello Thanks for the response. Im working on the SPIHT image Compression Algorithm. Iv calculated the DWT of a sample image on matlab, then designed the encoder and decoder on Verilog HDL. The decoded output is a 16X16 matrix on which i want to perform the Invserse DWT so i can recover the original image. My IDWT code (...)
nice. from there you can start counting the red pixels based on the RGB function, image(x,y,1:3)... where x and y is their coordinates while 1:3 will tell the RED, GREEN and BLUE values. since you want the RED pixels, then you can select your RED threshold values and count those pixels. count = 0; for i=1:m for j=1:n red =

Types of segmentation that can be used for denoising a gray scale image in matlab.
The ventral stream is described by the following route: v1--->v2--->v4--->IT Units of V1 (in S1 layer of) implement Gabor filters. In this layer, an input grayscale image (120x120 or 160x160) is densely filtered by a battery of gabor filters at each scale and orientation. Therefore, at each pixel of the input image, filters of each size a
Hi friends, i am planning to do a project in image processing. I wish to do a real time project since doing the same in software is common. So, i decided to use a DSP processor and burn the matlab code to the processor. A camera interface will capture images and process according to the burned code. I need a video/ image (...)
