Sebastian Frysztak	f06dc6cbc4	Add AVX version. It relies on some SSE2 instructions, so performance gain is not that huge (about 1.4x). I experimented with 256-bit loads, but they turned out to be slower (at least on Sandy Bridge).	8 years ago
Sebastian Frysztak	95c333cba5	SSSE3: use 16-bit weights. Overall, I'm very happy with performance of this code, but not so much with resulting image. It seems like integer approximations won't do. I might remove this code altogether, so I didn't update comments.	8 years ago
Sebastian Frysztak	72aec87047	Add SSSE3-based blur implementation. Calculations are done on integer, rather than floating point numbers, so this implementation is not as accurate (but when scale factor is reasonable enough, no artifacs are visible). It is, however, faster by a factor of ~3.	8 years ago
Sebastian Frysztak	3662b8e187	Improve border handling for larger kernels.	8 years ago
Sebastian Frysztak	afe41c5754	Extend kernel size to 15x15.	8 years ago
Sebastian Frysztak	fb5dbbe661	Add SSE2-optimized blur. About 4-6 times faster than naive implementation.	8 years ago
