Shi Tomasi Feature Detection

CUDA, OpenMP, and regular serial C implementations of Shi Tomasi feature detection. Done as a comparison of architecture project.

How to Use

usage: ./stfd [-v,-vv] <full path to the image> [sigma] [windowsize] [num_features]
flags:
	-h: show this help menu
	-v: output basic execution information
	-vv: output all information... good for debugging
arguments:
	sigma: the sigma value for the Gaussian distribution used to form the convolution mask.
	windowsize: the size of a pixel 'neighborhood' in an image
	num_features: how many features to extract

shi_tomasi_feature_detection's Issues

width height reversed

Thank you for making this available, it is incredibly helpful!

While playing with the serial implementation I noticed a bug in line 211 of stfd.c
eigenvalues[i].x >= image_height-1-ignore_x || eigenvalues[i].y >= image_width-1-ignore_y) {

The x should use width and the y should use height, instead of vice-versa.
