- Abstract
- Image analysis using deep learning has made significant progress in the last few decades, and the importance of pre‐processing input images has become evident. However, adapting a network structure suitable for input images has not been considered. In this study, a simple network adaptation method for color image analysis is described. The method is illustrated using semantic segmentation, which mainly takes a color image as input. The method is inspired by chrominance subsampling, which is a practical method for image and video analysis. The human visual system is less sensitive to color differences than it is to brightness, and based on this phenomenon, it is possible to improve existing networks by providing less resolution to chroma information than luminance information in the network encoder design by applying the group convolution concept. The proposed method helps to achieve improved results without changing the complexity of the baseline network model, and is especially helpful in applications with limited resources, such as autonomous driving, augmented reality. Experiments were performed on a combination of datasets (i.e. CamVid, Cityscapes and KITTI‐360) and networks (i.e. ENet, ERFNet, Deeplabv3plus with mobilenetv2). The results show that the method improves the performance of existing network structures without increasing the number of parameters.
