SLIC Superpixel Modification

We modified the SLICO version of slic algorithm to work with OpenCV2, and make it easy to use.

Class explanation

• void SLIC::GenerateSuperpixels(cv::Mat& img, UINT numSuperpixels)

  Perform SLIC algorithm on the given image with the given number of superpixels.

  img - 24-bit or 8-bit cv::Mat

  numSuperpixels - an appropriate number, no more than total number of pixels

• cv::Mat SLIC::GetImgWithContours(cv::Scalar color)

  Get the result image with contours on the given color.

  color - If input image is 24-bit, the color may be cv::Scalar(255, 0, 0) or cv::Scalar(0, 255, 0) or cv::Scalar(0, 0, 255)

  If input image is 8-bit, the color may be cv::Scalar(0) or cv::Scalar(128) or cv::Scalar(255)

• int* SLIC::GetLabel()

  Get label on each pixel which shows the number of superpixel it belongs to.

Example

• original image

• 200 superpixels

• 500 superpixels
