APPARATUS AND METHODS OF PRODUCING PHOTOREALISTIC IMAGE THUMBNAILS

摘要

Methods, systems, and machine-readable media for processing an input image (22) are described. In one aspect, respective visual features of local input image regions of an input image (22) having a first pixel resolution are analyzed to produce a result (26). Based on the result (26) of analyzing the visual features, reduced-resolution visual representations (30) of corresponding ones of the local input image regions are derived from the input image. A thumbnail image (24) that reflects the arrangements, proportions and local details of the input image (22) having a second pixel resolution lower than the first pixel resolution is produced from the reduced-resolution visual representations (30). The thumbnail image (24) is output.
