Comparison of Multi-level inverters by reducing common mode voltages and DC-link capacitor voltage balancing for IM drives

摘要

This paper introduces a new hybrid image the concept of image fusion of filtered noisy images for impulse noise reduction and enhancement approach driven by both global and local processes on luminance and chrominance components of the image. The filtered images are fused to obtain a high quality image compared to individually denoised images. In-order to better appraise the noise cancellation behavior of our fusion technique from the point of view of human perception, an edge detection is performed using canny filter for the fused image. This approach, based on the parameter-controlled virtual histogram distribution method, can enhance simultaneously the overall contrast and the sharpness of an image. The approach also increases the visibility of specified portions or aspects of the image whilst better maintaining image color. The experimental results have shown the superiority of the proposed approach1.
