A Shot boundary Detection Technique based on Visual Colour Information

The paper proposes a novel video segmentation system with maiden application of CIEDE2000 colour-difference and mean luminace pattern. CIEDE2000 colour-difference uses Lab colour space which is a stable and efficient colour space. The main advantage of Lab colour space model is that it can approximate all the available colours perceived by our human eye. CIEDE2000 colour difference is used for detecting abrupt transitions in the video. The novel contribution of the paper is the maiden use of the mean luminance pattern, increasing and decreasing patterns of the mean value of frame luminance, for detecting the gradual transition. The approach is validated on standard databases TRECVid 2001 and 2007 test video database. The performance of the proposed technique is compared with recently reported techniques and found to be superior as compared to other techniques. The accuracy achieved with the proposed method on the standard databases is 95.9% for cut transition, 78.6% for gradual transition and 92.1% overall.

Four Input Single Output based third order universal filter using Four Terminal Floating Nullor

This paper presents a Four Input Single Output based third order universal filter that offers all five sections of filter frequency responses with some passive components using active block named as Four Terminal Floating Nullor (FTFN). The design schematic uses two number of Four Terminal Floating Nullor (FTFN) with three numbers of resistors and capacitors each. The proposed universal filter is realised with CMOS implementation of FTFN as well as Current Feedback Operational Amplifier (CFOA) namely IC AD844 for FTFN realisation. The viability of the universal filter circuit is justified with PSPICE simulation that includes both CMOS and AD844 based realization of FTFN. Also theoretical verification is well performed for the sustainability of the proposed circuit along with experimental verification by using IC AD844.
