Abstract

In this paper, we are going to describe the performance characteristic of very high resolution image processing with WebCL on the web environment. In order to evaluate the variance of the execution time by WebCL, we modified the Pixastic library, one of the most representative image processing libraries written in JavaScript, by using WebCL. We achieved a speedup of up to 4.2 times and 2.8 times on average against the original one for the image of 8K Ultra HD with the WebCL-based library.

본 논문에서는 웹 환경에서 WebCL을 이용한 초고해상도 이미지 처리 기법의 성능을 분석하고자 한다. WebCL로 인한 성능의 변화를 측정하고 평가하기 위해 자바스크립트로 작성된 대표적인 이미지 처리 라이브러리인 Pixastic 라이브러리를 WebCL 기반의 코드로 수정하였다. WebCL 기반 라이브러리는 8K Ultra HD의 이미지에서 기존 라이브러리 대비 최대 4.2배의 성능 향상을 얻을 수 있었으며 평균적으로 2.8배의 성능 향상을 얻을 수 있었다.
