Evaluating the performance of max current AC-DCT based colored digital image fusion for Visual Sensor Network's

This paper presents an efficient digital image fusion strategy that is created for Visual Sensor Networks(VSN's) to work in resource restricted, hazardous environments like battlefields. We aimed to use multiple partially unfocused colored images to develop a single multi-focus image using Discrete Cosine Transformation(DCT) depending on maximum value Alternating Current(AC) coefficients. This technique is beneficial in computation restricted environments of reduced computational powered devices to achieve image quality of higher degree. Our experiments shown that, the evaluated technique had produced better quality images as compared to other available methods of fusion in DCT domain.
