Journal ArticleDOI
Dynamic contrast enhancement based on histogram specification
TL;DR: The experimental results show that the proposed dynamic histogram specification (DHS) algorithm not only keeps the original histogram shape features but also enhances the contrast effectively.
Journal ArticleDOI
Fast and efficient median filter for removing 1-99% levels of salt-and-pepper noise in images
TL;DR: The proposed median filter restores corrupted images with 1-99% levels of salt-and-pepper impulse noise to satisfactory ones by intuitively and simply recognizing impulse noises, while keeping the others intact as nonnoises.
Journal ArticleDOI
Illumination-Sensitive Background Modeling Approach for Accurate Moving Object Detection
TL;DR: An illumination-sensitive background modeling approach to analyze the illumination change and detect moving objects and demonstrates the effectiveness of the proposed approach in providing a promising detection outcome and low computational cost.
Journal ArticleDOI
Adaptive thresholding algorithm: Efficient computation technique based on intelligent block detection for degraded document images
TL;DR: Experimental results demonstrate the effectiveness of the proposed method in providing a promising binarization outcome and low computational cost.
Journal ArticleDOI
Low-power and high-quality Cordic-based Loeffler DCT for signal processing
TL;DR: The proposed Cordic-based Loeffler DCT is very suitable for low-power and high-quality encoder/decoders (codecs) used in battery-based systems and retains the good transformation quality of the original Loeffer DCT.
