UDP – a New Universal Demosaicing Pipeline Algorithm for RGB Color Filter Arrays
نویسنده
چکیده
A new universal demosaicing algorithm suitable for imaging pipelines using a RGB color filter array (CFA) is proposed. The proposed algorithm can reconstruct single-sensor images registered by a digital camera equipped with any RGB CFA currently in use. The algorithm includes a spatio-spectral interpolation model, a new edge-detection technique, and a post processing to reduce the color shifts and artifacts of the reconstructed image. Experimental results over various test CFA patterns and real images demonstrate the efficiency and feasibility of a proposed universal demosaicing algorithm. Two methods – objective metrics (mean squared error – MSE and peak signal to noise ratio – PSNR) and subjective evaluation are used to analyze the results.

Automating the design of image processing pipelines for novel color filter arrays: Local, Linear, Learned (L) method
The high density of pixels in modern color sensors provides an opportunity to experiment with new color filter array (CFA) designs. A significant bottleneck in evaluating new designs is the need to create demosaicking, denoising and color transform algorithms tuned for the CFA. To address this issue, we developed a method(local, linear, learned or L) for automatically creating an image processi...
متن کاملLagrange Based Color Image Demosaicing Using Iterative Residual Interpolation
Interpolation technique in color image demosaicing is a big challenge to obtain RGB channels as perceived by humans. The existing demosaicing methods adopt i terative residual interpolation (IRI) technique, which performs iterations on the residuals. These methods are unable to reconstruct G channel efficiently with less iterations. Hence a new demosaicing method is proposed, which performs les...
متن کاملColorization-Based RGB-White Color Interpolation using Color Filter Array with Randomly Sampled Pattern
Recently, several RGB-White (RGBW) color filter arrays (CFAs) have been proposed, which have extra white (W) pixels in the filter array that are highly sensitive. Due to the high sensitivity, the W pixels have better SNR (Signal to Noise Ratio) characteristics than other color pixels in the filter array, especially, in low light conditions. However, most of the RGBW CFAs are designed so that th...
متن کاملAdaptive color demosaicing and false color removal
Color interpolation solutions drastically influence the quality of the whole image generation pipeline, so they must guarantee the rendering of high quality pictures avoiding typical artifacts such as blurring, zipper effects and false colors. Moreover, demosaicing should avoid emphasizing typical artifacts of real sensors data, such as noise and green imbalance effect, which would be further a...
متن کاملFalse colors removal on the YCr-Cb color space
Postprocessing algorithms are usually placed in the pipeline of imaging devices to remove residual color artifacts introduced by the demosaicing step. Although demosaicing solutions aim to eliminate, limit or correct false colors and other impairments caused by a non ideal sampling, postprocessing techniques are usually more powerful in achieving this purpose. This is mainly because the input o...
