SC

A Seam Carving algorithm implementation in Go with:

• CPU-only
• Uses all CPU cores in parallel
• Supports PNG, JPEG files
• Supports reduce image size
• Supports increase image size
• Supports region protection (imgMask green)
• Supports region erasure (imgMask red)
• Polish API

Usage

go get -u github.com/zrt/SC

import "github.com/zrt/SC"

Example

package main

import . "github.com/zrt/SC"

func main() {

	img := LoadJPEG("input.jpg")

	energyFunc := L2NormEnergyFunc
	energyImg := SliceToImg(energyFunc(img, 1+2))
	// show energy img
	SavePNG(energyImg, "img_energy.png")

	newImg, newImgSeam := Resize(img, energyFunc, 1280*8/10, 868*8/10, nil)
	SavePNG(newImg, "output.png")
	SavePNG(newImgSeam, "output_seam.png")
}
