Information Measure Based Tone Mapping of Outdoor LDR Image for Maximum SIFT Extraction

A novel tone mapping method referred to here as information measure-based tone mapping is proposed for extracting the maximum number of scale-invariant feature transform (SIFT) feature points from outdoor low dynamic range (LDR) images. To this end, first, an image is transformed to YUV colour space in which every pixel is assigned two information scores: forward and inverse scores. The forward an...
