Odes to Oats / Circle Detection and Color Quantization

Circle Detection and Color Quantization

Computer Vision Project

Language: Objective-C

Frameworks: Accelerate

Repository: Github

 

Image 1:

Hough circle detection.

  • Wrote Canny Edge Detector with adjustable thresholding.
  • Thresholded edges cast votes to make up Hough space for adjustable radius.

 

Image 2:

Color quantization in RGB space (k-means = 2).

  • Wrote  K-means for quantizing color in 3-Dimensional RGB space.

 

Image 3:

Color quantization in HSV space (solely on Hue, k-means = 3).

  • Wrote K-means for quantizing hue.
  • Wrote methods for conversion between RGB and HSV space.
