I need an algorithm that can determine whether two images are 'similar' and recognizes similar patterns of color, brightness, shape etc.. I might need some pointers as to what parameters the human brain uses to 'categorize' images. .. I have looked at hausdorff based matching but that seems mainly for matching transformed objects and p...
Here's what I would like to do: I'm taking pictures with a webcam at regular intervals. Sort of like a time lapse thing. However, if nothing has really changed, that is, the picture pretty much looks the same, I don't want to store the latest snapshot. I imagine there's some way of quantifying the difference, and I would have to empi...
What is the efficient way to compare two images in visual c..? Also in which format images has to be stored.(bmp, gif , jpeg.....)? Please provide some suggestions ...
I have used the SIFT implementation of Andrea Vedaldi, to calculate the sift descriptors of two similar images (the second image is actually a zoomed in picture of the same object from a different angle). Now I am not able to figure out how to compare the descriptors to tell how similar the images are? I know that this question is not ...
Hey folks, After reading many related posts on this site on the subject of image comparison I'm thinking I'll try implementing a PCA on each image in order to see if an image is 'similar' or not, but I'm not sure how to get the data from my images - is there a VB function that I can use to convert the image into an array of bytes or som...
I have a series of images. Each one is typically (but not always) similar to the previous one, with 3 or 4 small rectangular regions updated. I need to record these changes using a minimum of disk space. The source images are not compressed, but I would like the deltas to be compressed. I need to be able to recreate the images exactl...
I have made a videochat, but as usual, a lot of men like to ehm, abuse the service (I leave it up to you to figure the nature of such abuse), which is not something I endorse in any way, nor do most of my users. No, I have not stolen chatroulette.com :-) Frankly, I am half-embarassed to bring this up here, but my question is technical an...
Are there any Open Source Digital Video Fingerprinting initiatives? ie: Something that could compare two video files of disparate quality but indicate they are of the same event, program etc. ...
i am going to develop an application for image comparison on java. For this i have choosen euclidean algorithm. This application involves with 2 images. 1. Actual image 2. Part of the actual image. Algorithm should compare the part of the image with actual image. If the part is existed in actual image, it should return one value as matc...
