Two LSIs for real-time video signal processing have been developed; One a videosignal processing LSI (called the Picot) which can process dynamic images (time-varying images) at video rate (14.3MHz); and the other a network LSI (called the Picot-net) which connects a number of Picots and makes possible multi-processing. The Picot and the Picot-net have an architecture suitable for image signal ...

Identification and verification of a video clip via its fingerprint find applications in video browsing, database search and security. The video is collapsed into a short fingerprint using a robust hash function based on signal processing operations. We propose two robust hash algorithms for video based on the Discrete Cosine Transform. The robustness and randomness properties of the proposed h...

Multimedia signal processing, or media processing [1], is the processing of digital multimedia information in a programmable processor. Digital multimedia information includes visual information like images, video, graphics and animation, audio information like voice and music, and textual information like keyboard text and handwriting. With general-purpose computers processing more multimedia ...

Liquid Crystal Displays (LCDs) have improved so dramatically over the past years, that they have rapidly overtaken the TV market. At the moment, one major aspect where LCDs are still inferior to the traditional Cathode Ray Tube (CRT), is the resolution of moving images, i.e. dynamic resolution. In this paper, we review some of the proposed methods to improve this aspect, from a video signal pro...

introduction automatic human emotion recognition is one of the most interesting topics in the field of affective computing. however, development of a reliable approach with a reasonable recognition rate is a challenging task. the main objective of the present study was to propose a robust method for discrimination of emotional responses thorough examination of heart rate variability (hrv). in t...

In this paper we introduce wavelet video processing of proximity sensor signals. Proximity sensing is required for a wide range of military and commercial applications, including weapon fuzing, robotics, and automotive collision avoidance. While our proposed method temporarily increases signal dimension, it eventually performs data compression through the extraction of salient signal features. ...

Existing multimedia processors having millions of transistors are not suitable for portable multimedia services and existing fixed-point DSP chips having fixed data formats are not appropriate for multimedia applications. This paper proposes a multimedia fixed-point DSP (MDSP) chip for portable multimedia services and its chip implementation. MDSP employs parallel processing techniques, such as...

Compressed Video Enhancement using Regularized Iterative Restoration Algorithms Passant Vatsalya Karunaratne Many applications, ranging from scienti c applications to consumer electronics products, use the acquisition and processing of digital video. The acquisition, compression, transmission, and format and rate conversion of an information carrying video signal degrades the accurate represent...
