Compare Two Images
What are the properties of an image that can be compared for taking the percentage of matching between two images? Like std2(), we can take the std2() value of two images and then simply take the percentage of the two. After that we can compare between the two. Is there anything else like this function in matlab? Plea... 21 Apr 2010 00:06

save keypoint descriptors
hi every one, I am doing project on image comparison using SIFT algorithm for keypoint detection. To increase the performance of image retrieval I was thinking of storing the descriptor in the database. But since descriptor is a matrix I am not getting how to save the descriptor. please give me some idea to do this... 23 Apr 2010 01:22

problem using sift for matching
hi everyone, I am doing a project on image comparison. I am using SIFT for determining the keypoints of the images and then using NNS(Nearest Neighbour Search) for comparing the two images. My problem is that, when I am comparing an image with its flipped image, it is not showing any matched keypoints. But on compari... 20 Apr 2010 22:59

PWM transfer function
Hi guys, I built a PWM converter model with Simulink/ Simpower system blockset. Now need to do some mathematical analysis on it. I've got the converter transfer function, but was wondering how to obtain the PWM transfer function. Is there any general expression for PWM transfer function that by numerically substituti... 20 Apr 2010 21:53
