Hi, I am trying to find the width and height of my bounding boxes. I have each image and bounding boxes around each moving object. Now i must find the width and height and centre of mass and average colour for each. Any ideas on how to achieve this? So far I have used regionprops to obtain the centroid and the bounding box. Any easier or more efficient ways??

I'm working with about 1000 images, which are read into matlab as matrix. But due to variation in the intensity of light(weather condition, AC light) during the time the pictures are taken, there is a variation in the pixel value reported in the images. I want to make all pictures to have the same brightness. This means if I should index the image matrix at a point, all the images should have the ...

hi, I am currrently working with matlabs image acquisition tool box. The problem is that when ever I use ctrl C to stop a running code, I must use a memory clearing statment called imaqreset to clear some memory buffer somewhere. Owing to matlabs incredibly 'smart' memory allocation schemes, if there is a slight delay in clearing the memory buffer, then every thing slows down and eventua...

hi, I am currently working on matlab version 6. I saw a demo for running 2d dct. Its heading was "2 D DCT image compression demo". But does the algorithm behind it uses any compression procedures like VLC or something?? Is the compression achieved here without using any compressing tech? Someone pls , clear my doubt!!!!!!

Hi everyone, i would like to know how to get an affine transformation matrix of frame1 and frame2 of an unstable video in avi format. Matlab examples only provide information in applying the affine matrix to an image. Im not sure if functions like imtransform and maketform can give me the affine parameters of such unstable video frame. Hope to hear some feedback. I will greatly apprec...
