In this paper, we present a superpixel generation method for spherical images, which cover 360° field-of-view. Unlike previous works that directly use existing superpixel algorithms on unrolled spherical images, our approach explicitly considers the geometry for spherical images and uses sphere as the underlying representation. For quantitative evaluation, we make a spherical image segmentation database...
Abstract-Shortwave power amplifiers (PAs) are nonlinearization and their features are changed with many kinds of factors such as the temperature of environmental, electrical aging, at the same time they have strong memory effection. In this paper, an indirect learning architecture and digital pre-distortion have been adopted, MDS algorithm applied in adaptive pre-distortion amplifier system of optimizes...
