COMBINED GAUSSIAN FILTERING, DWT AND MORPHOLOGICAL APPROACH FOR SATELLITE IMAGE ENHANCEMENT

Morphological Filtering for Image Enhancement and Detection

Linear Filtering for Optimized Approach in Satellite Image Enhancement

Problem statement: For decades, several image enhancement techniques have been proposed. Although most techniques require profuse amount of advance and critical steps, the result for the perceive image are not as satisfied. Approach: In this study, we proposed a new method to enhance the satellite image which compares two procedures using two different kinds of filtering technique with an addit...

DWT and PCA Based Image Enhancement with Gaussian Filter

A new satellite image contrast enhancement technique based on the Discrete Wavelet Transform (DWT) and Principal Component Analysis has been proposed. By the use of discrete wavelet transform, the input image decomposed into four frequency sub-bands and estimates the eigen values and eigen vectors (PCA) of the low–low subband image and reconstructs the enhanced image by applying inverse DWT. Th...

Satellite Image Enhancement using Discrete Wavelet Transform and Morphological Filtering for Remote Monitoring

Background: Satellite images are being used in many fields of research mainly for monitoring the remote areas for analyzing the environmental conditions, land and water resource monitoring etc., these images are affected by clouds and electromagnetic radiation which results in poor perception of image. Objective: To analyze the satellite image, improvement in the resolution of the image and als...

Satellite Image Resolution Enhancement By Using Discrete Wavelet Transform (DWT)

Bicubic interpolation is more sophisticated than the other two techniques and produces smoother edges. Wavelets are also playing a significant role in many image processing applications. The 2-D wavelet decomposition of an image is performed by applying the 1-D discrete wavelet transform (DWT) along the rows of the image first, and then the results are decomposed along the columns. This operati...
