A Optimized VLSI Architecture for Full-HD Modified Gradient Guided Image Filter

Abstract

In the field of computer graphics and computerized visual imaging systems, filtering is an effective topic with intensive research interest. The main difficulty among the approach is the edge-preserving technique. Even the many filtering concepts have employed but still, the critical approach concepts in real-time filters are quite hard to prevent. So this modified gradient image filtering approach has been proposed which satisfies the requirements of the edge preservation in the digital images with completely more precision. Edge-preserving filtering technique aims to implement denoising of an image thus preserving or emphasizing important information about the structure. Modified-Guided Image Filtering technique has been implemented to address the two issues edge-preserving filtering processing quality issues and the low-powered computational complexity.
The proposed design decreases computational complexity and improves efficiency, solving the problem of global parameters, decreasing circuit area and processing time, and removing bottleneck speed by simplifying the complex exponentiation procedure.
