Abstract
Land cover classification of remotely sensed images is an extremely important and challenging task. During the last two decades, several methods have been proposed to deal with this problem. In particular, convolutional neural network (CNN)-based methods for land cover classification have enjoyed high popularity due to their strong feature extraction and characterization abilities. However, most CNNs-based methods use relatively small kernels (usually, 3 x 3 pixels in size). Increasing the size of the kernel introduces a lot of parameters and renders considerable computational overloads. To address this issue and allow for the processing of large image datasets, the pyramidal convolution (PyConv) network has been adopted. PyConv network contains several levels of kernels with varying scales and depths, and shows significant improvements in the task of visual recognition. In this paper, we evaluate the performance of the PyConv network on the UCMERCED dataset. Our experimental results reveal that the considered approach exhibits good performance and high efficiency in the task of land cover classification.
