SCAB Output Enhancement: 1x1 Convolution for Image Refinement

The output of the SCAB is fed into a 1 ￗ 1 conventional convolution layer with a single kernel, the output of which is added elementwise to the prior fine image Fy through a skip connection. Thus, the final fine image is generated. This approach utilizes a 1x1 convolution layer with a single kernel to enhance the output of the SCAB. The output of this layer is then added element-wise to the prior fine image Fy through a skip connection, resulting in a refined final fine image. This method effectively leverages the spatial contextual information captured by the SCAB and enhances the overall image quality.
