Recent studies have shown that panchromatic colour filter arrays possess better light intensity properties than the more prevalent Bayer array. This is an attractive property in integrated camera design. Demosaicking algorithms, however, focus primarily on Bayer-based cameras because of their simple demosaicking process. This paper presents a novel algorithm for use in the RGBW class of panchromatic...
Because of false detection rate, many fire detection algorithm cannot easily become a part of alarm monitoring system, so in this paper, we proposed to detect fire precisely with color variation in temporal domain to reduce false detection rate. By capturing special characteristic of fire in temporal domain, we can get reliable experimental result tested by 24 video sequences. With our algorithm,...
In this paper, an error surface-considered modeling algorithm for quarter-pixel motion estimation during video encoding is presented. We previously proposed two algorithms: a model-based quarter-pixel motion estimation (MBQME) algorithm and a hierarchical modelbased quarter-pixel motion estimation (HMBQME) algorithm. MBQME is an interpolation-free algorithm that has a minimum motion estimation time,...
