- Abstract:
-
Current multilayer perceptron (MLP)-based models usually require flattening pixels on an image and subsequently enforce a self-attention mechanism or “Mix” enhancement scheme to achieve global modeling of images and obtain long-range dependence of the image. However, these approaches generally consume considerable computing resources to bridge the loss of spatial topological information in image reconstruction. Particularly for UHD image dehazing tasks, numerous stacked MLP models suffer from memory overflow when running a UHD-hazed image on a resource-constrained device. A novel model for real-time dehazing of 4 K images on a single GPU (110 fps) is proposed here to address this issue. This model is advantageous because it maintains spatial information of the raw image and has low computational complexity.
