Selected Problems of Color Image Demosaicing in Security Imaging

Popis výsledku v původním jazyce

The color TV security cameras are mostly based upon a single-sensor configuration with on-chip CFA. 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 are numerous interpolation algorithms suitable for the demosaicing - recalculation of full resolution R G B rasters. The paper is devoted to the comparison of several selected demosaicing algorithms usually applied in image enhancement of natural images where the subjective image quality is crucial. Our approach is oriented to the evaluation of identification limits in presence of noise and we are studying the noise resistivity of various demosaicing algorithms.
