Category Independent Object Detection

Implementation of Object Detection algorithm:

Matlab implementation of the object detection algorithm [1] (2011-11-04, ver 1.1)

Readme and License


  1. The algorithm needs the executables of Pedro F. Felzenszwalb's and Daniel P. Huttenlocher's superpixel segmentation algorithm. You can download the code from: Felzenszwalb's page.

  2. The code includes the SS feature developed and described [2]. If you use results derived from this code in your publications, please cite [1], [2], and [4].

Precomputed windows for VOC2007 dataset:

VOC 2007 boxes (Obtained using VOC training data)

VOC 2007 boxes (Obtained using training data from [2])

Performance evaluation:

Recall-overlap curves, computed using methods described in [1], [2], and [3].
