Abstract

Due to light dispersion and absorption, underwater photographs often exhibit colour distortion and reduced visibility. Existing techniques make use of a variety of presumptions and constraints to arrive at plausible improvements for underwater picture enhancement. The accepted assumptions may not hold true for some scenarios, which is a typical shortcoming of these methodologies. This research offers an end-to-end architecture for underwater image enhancement to solve this issue and introduces D-CNN, a CNN-based network. Color correction and haze removal are the two exercises used to train the D-CNN. With this dual training method, it is possible to concurrently learn a powerful feature representation for both tasks. The suggested learning framework considerably enhances the convergence speed and accuracy by using a pixel disruptive method to better extract the intrinsic characteristics in local patches. We create 200000 training photos based on the physical underwater imaging model to manage the training of D-CNN. Benchmark underwater photographs were used in experiments to compare D-CNN performance to those of other approaches.
