FD-Vision Mamba for Endoscopic Exposure Correction
This addresses image quality issues for healthcare professionals in endoscopic procedures, representing an incremental improvement with a novel hybrid method.
The paper tackles exposure abnormalities in endoscopic imaging by proposing FD-Vision Mamba (FDVM-Net), a frequency-domain network that reconstructs images using a C-SSM block to integrate local and long-range features, achieving state-of-the-art results in speed and accuracy for arbitrary resolution images.
In endoscopic imaging, the recorded images are prone to exposure abnormalities, so maintaining high-quality images is important to assist healthcare professionals in performing decision-making. To overcome this issue, We design a frequency-domain based network, called FD-Vision Mamba (FDVM-Net), which achieves high-quality image exposure correction by reconstructing the frequency domain of endoscopic images. Specifically, inspired by the State Space Sequence Models (SSMs), we develop a C-SSM block that integrates the local feature extraction ability of the convolutional layer with the ability of the SSM to capture long-range dependencies. A two-path network is built using C-SSM as the basic function cell, and these two paths deal with the phase and amplitude information of the image, respectively. Finally, a degraded endoscopic image is reconstructed by FDVM-Net to obtain a high-quality clear image. Extensive experimental results demonstrate that our method achieves state-of-the-art results in terms of speed and accuracy, and it is noteworthy that our method can enhance endoscopic images of arbitrary resolution.
