Pixel data is received, and connected pixel components are identified. The connected pixel components are associated with segments. Spatial invariant features are extracted for each of the segments, and keys are acquired for each segment. The features and keys are associated with one another and indexed in a data store for subsequent retrieval.Field of SearchImage segmentation using colorIMAGE SEGMENTATION Segmenting hand-printed characters PATTERN RECOGNITION On-line recognition of handwritten characters Writing on ordinary surface (i.e., electronics are in pen) Feature extraction Counting individual pixels or pixel patterns IMAGE TRANSFORMATION OR PREPROCESSING Image storage or retrieval | |
