go-cv is a computer vision and image processing library for Go using Golang assembly. It is a works-in-progress wrapper around the Simd library. For now most work has been done on the SSE2 version.
The Simd Library is a highly optimized image processing library. It provides many useful high performance algorithms for image processing such as:
- pixel format conversion
- image scaling and filtration
- extraction of statistic information from images
- motion detection
- object detection (HAAR and LBP classifier cascades)
- classification
- neural network
The algorithms are optimized using different SIMD CPU extensions. In particular the library supports following CPU extensions:
- x86/x64: SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX and AVX2
- ARM: NEON
$ go get -u "github.com/fwessels/go-cv"
See the samples directory for various sample algorithms. For example:
$ cd samples
$ go run filtering.go
A comparison against go-opencv shows the following results:
