Image enhancement is an indispensable technique in improving the quality, brightness, contrast and clarity of satellite images. The object that appears images variation caused by shadow, occlusion, camouflage are fundamental challenges posed image techniques. aim this research work was to enhance Sambisa using histogram equalization technique. MATLAB 2021 used implement experiment. results show...

In this paper, contrast enhancement of dark image using Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT) coefficients is proposed. Then the contrast enhancement is obtained by applying Dynamic Stochastic Resonance (DSR).The goal of dark image enhancement is to clearly visualize the features of the image. Two different coefficients DCTand DWT are used for implementing contras...

In this paper we describe a method we developed for selective detection and enhancement of image feature patterns. A set of directional basis filters were designed to detect the image features of interest, and a steerable pyramid transform [1,2] is used to generate a multiscale representation of the image features that has desirable shift and rotation invariance. By analyzing and selectively pr...

Target detection via digital image processing is crucial to biomedical diagnosis and homeland security. Both image contrast enhancement and image segmentation are among the most practical approaches of image processing. Under conditions of improper illumination and unpleasant disturbances, adaptive image enhancement can be conducted, which adapts to the intensity distribution within an image. I...
