Project 5: Object Detection

I. Visualization

This is the test image:

HOG feature and SVM weights, and an example of detection results:

TIG feature and SVM weights, and an example of detection results:

II. PR Curves

PR curves on the cropped image dataset:

PR curves on the pedestrian dataset:

III. Extra Credits

We only did one extra credit: for each pixel, we make it contributes to not only its own cell but also the four adjacent cells, and a gaussian kernel is used for weighting.
