The color TV security cameras are mostly based upon a single-sensor configuration with on-chip CFA (color filter array, Bayer configuration). The impact of different spatial sampling rasters in R G B channels causes an additional image distortion. In the field of security technology the identification task is among very frequent and above-mentioned sampling effect can affect it significantly. There...
This paper presents a new image-processing (IP) pipeline adopting an image-processing approach via nonlinear image-decomposition, for a digital color camera. This new IP pipeline is composed of four stages. At the first stage, with the multiplicative BV-G image-decomposition method, each primary color channel of observed raw color data mosaicked with the Bayer color filter array is decomposed as a...
We present a novel algorithm based on Beamlet Transform for extracting seam edges from noisy welding images. Taking into account of some special characteristics of welding image processing, we introduce an orientation-thresholding step as well as a two-scan method to the standard beamlet-based line detection algorithm. Experiments are conducted to extract edge features from noisy welding images at...
Colour edges are sharp boundaries between two distinct colours. Most existing demosaicking methods depend on assumptions which will be invalid at edges. In this paper, we apply a method that avoids interpolation across an edge by extrapolating estimates in four different directions. In order to improve colour edge preservation, we propose a novel classifier to select the best estimate in conjunction...
