Tone-mapping operators are used to produce low dynamic range versions of the high dynamic range images, while preserving as much details as possible. We have proposed a tone-mapping operator which is built on an existing histogram adjustment technique. It incorporates certain characteristics of the human visual system, to restrain the problem of extreme contrast enhancement of certain segments and...
In the current Internet age, there is a need for a set of good tools for copy detection purposes, as well as enhanced navigation, indexing and searching. We tackle this problem using an ordinal method. This paper presents an extension to our earlier work on an algorithm for generating a video signature based on an ordinal measure. We have achieved precision and recall of 0.935 and 0.966 respectively...
This paper presents an approach for music feature analysis with an application in dance animation, in which a dancing avatar dances according to the rhythm and energy of the music. Extracted music features, such as drum beats and meters, are used for synchronization with motion sequences from a database of dance animation files. In addition, music segmentation with music intensity labels are produced...
We demonstrate a method in which gesture control is enabled through use of a stereo camera. Hard to use keyboard commands are effectively emulated using positional gestures. We describe the implementation and some results from user surveys based on user's trying the application at a public exposition. Along with outlining the implementation, we report the initial findings and show evidence as to why...
