Image segmentation using template prediction
First Claim
Patent Images
1. Method for segmenting images into groups of segments, said segments being based on image features, with the steps of:
- a) determining a group of pixels for segmenting, b) determining for said group feature characteristics, c) determining from neighboring groups segment templates, said segment templates describing constant or continuous features within said neighboring groups, d) calculating for said group error values by comparing features of said group with features of said segment templates, and e) deciding to assign said group to one of said segment templates, or to create a new segment template based on said error values.

Abstract
The invention relates to image segmentation using templates and spatial prediction. The templates of neighboring pixels are used for predicting the features of a current pixel. The pixel is assigned to the segments of neighboring pixels according to the deviation of its features from the templates.
