First Claim
Patent Images
1. A method for processing a color tissue image comprising:
- generating a matrix of feature vectors, wherein each feature vector corresponds to a respective pixel of a tissue image and describes color and texture features of the respective pixel;
selecting a subset of feature vectors from the matrix of feature vectors;
deriving a set of colors and textures using the tissue image and the subset; and
generating an initial segmented tissue image using the set of colors and textures and the tissue image.

Abstract
The present techniques provide for the processing of color tissue images based on image segmentation. In an exemplary embodiment, the color and texture features of pixels in a tissue image are used to generate a matrix of feature vectors. A subset of feature vectors is selected from the matrix of feature vectors and a set of colors and textures are derived using the tissue image and the subset of feature vectors. An initial segmented tissue image is then generated from this set of colors and textures.
