Hi All
i need to ask if it is possible to create a feature vector from the image below by obtaining only the coordinates of white pixels using find(image) and put them in a vector or not ? and then i will create the training set by taking the coodinates of white pixels for 4 similar images ? after that i will perform dimensionality reduction algorithm such as LLE ,laplacian eigenmap ,LDA and matching algorithm ,is this possible or i must use a feature extraction algorithm such as surf or sift?
this is an image:
thanks to all
