Abstract

Writing image processing in WebAssembly enables the development of highly portable libraries. However, since WebAssembly is a new technology, there are not enough libraries available, and it is only supported by OpenCV. However, OpenCV has not been optimized specifically for WebAssembly. Therefore, in this paper, we develop native code using WebAssembly and compare it with OpenCV’s Gaussian filter using the separable Gaussian filter, a classical acceleration method for Gaussian filters. Experimental results showed that the Separable Gaussian filter was faster than OpenCV by performing vector operations in WebAssembly.
