Abstract:In this paper, a novel contrast enhancement algorithm is proposed which based on Histogram Specification. In order to keep original visual features, we extract the differential information from input video histogram. On the other hand, we also apply others parameters to control overall processing, such as frame direct current. Moreover, our Dynamic Histogram Specification leads more human sensitive than the other algorithms which based on histogram modification. It is worth to notice that our algorithm can be used in consumer applications, especially in mobile handset.
