chandnii7 / Corner-Detection

Program for Harris Corner Detection with non-maximum Suppression, HOG Feature Extraction, Feature Comparison, Gaussian Noise and Smoothing.

Corner Detection and HOG Feature Comparison

Objectives:

1. Gaussian Noise and Smoothing
2. Harris Corner Detection
3. Non-maximum Suppression
4. Corner Localization
5. Extract Feature Vectors with HOG
6. Feature Comparison

Interactively controlled parameters:

• Variance for gaussian (scale)
• Smoothing value for gaussian smoothing (filter size)
• Neighborhood size for computing the correlation matrix
• Weight of the trace in the Harris corner detection
• Threshold value for non-maximum Suppression

Program was implemented using Python and OpenCV. Refer the report for further implementation details and instructions to run the code: View Report

Results:
