Abstract

In recent years, image quality has been regarded as important by improving display technology. The most common method for improving image quality is image enhancement, and estimation of high frequency components is important for image enhancement, but it is important to consider color in the case of color images. In this research, I propose a resolution enhancement of color image using Laplacian pyramid. Conventional research assumes images of one channel, and there was a problem that color can not be preserved if the resolution of three channels of the color image is independently increased. In this research, I tried to increase the resolution in the HSV space, and improved this problem by using bicubic interpolation to expand saturation and hue. I also defined a new bicubic pyramid and examined its effectiveness.
