Abstract

Underwater image enhancement is one of the challenging tasks in the field of marine species. While dealing to work in the marine class, the researchers face some problems related to the underwater images. As the depth of water increases, the problems related to clear image capturing becomes more. The problems vary according to the type of water, amount of light, depth of water, the distance between camera and object, etc. This paper deals with the underwater image enhancement by working on the resolution and contrast factors to preserve the information of an original image. The proposed system uses Discrete Wavelet Transform (DWT) method to enhance the quality of underwater images. A Field Programmable Gate Array (FPGA) is a reconfigurable hardware, providing better features than DSP and other hardware devices due to their product fidelity and sustainable advantages in digital image processing. FPGA has a large impact on image and video processing; this is due to the potential of the FPGA to have parallel and high computational density as compared to a general purpose microprocessor. This paper proposes underwater images enhancement by wavelet decomposition based image fusion implementation on FPGA. The color corrected and contrast-enhanced images are fused which are withdrawn from an original underwater image.
