This is called SEGMENTATION .There are several types of it and it depends of what are teh OBJECTS and the quality of the image .
But before segmentation can be done .The image has to be processed in order to put it in "good condition" .This can be getting rid off color resolution, croppig just the area where the object is ,adjusting contratst and brightness etc .So is better to read a book about Image processing before arriving to that LAST PART that is segmentation .Then you need to know what to do with an object .How to characterize it in software .So i recommend to use CVIPtools and the book associated with it .
A particular processing is the Features Extraction. Generally, You can see your Image Corrupted by Noise, how a Random Process. Then, You apply the classical algorithms how Maximum Likelyhood Estmation and Minimun Distances Algorithms.
entire books about all the different method's of object extraction have been written, i assume you are talking about 2d object recognition from an image as opposed to a video. look for a book by yali amit "2d object detection and recognition" from mit press,
anto
first u have to separate the object from back ground (segmentation).
For the segmentation, first u have to decide the threshold of ur image.(i prefer otsu's method for auto threshold)
then do binarization fo ur image by placing 255 if pixel value is greater then threshold else place zero.
so u get ur object separate from background.
then run any edge detection algorithm(sobel) and catch ur object.
Anthor method is centroid algorithm.(its perfact for object tracking)
hi
i am working in the project ''image segmentation using pyramid algorithms".i want to know how to calculate the number segments of a segmented image .plz send the matlab code for it.in this email id bmeher1981@gmail.com.

Color Imageprocessing is very interesting, so the knowledges in Color theme should well be in you hands. the other reason may that the spectrum of light had shown space or band of energy, expectially impotant in systhesis work and analysis with time limited if quality needed.
