Installing OpenCV on Debian Testing

Here are the instructions to install OpenCV 2.4.9 on Debian Testing (7.x)

Message for new users

If you are a new Debian user, try installing OpenCV from repositories. As root:

aptitude install libopencv-dev

Reasons to install OpenCV manually

  • Debian does not pack the non-free OpenCV module
  • Sometimes you want to compile extra features such as OpenCL, Qt, or Intel TBB
  • You should know that this solution does not follow the DFSG

Diagnostic

Step 0: Check "natural" dependencies on Debian

Video Summarization Paper Presented at IEEE ISM 2013

We present our paper titled “Speeded-up Video Summarization Based on Local Features” at IEEE International Symposium on Multimedia (ISM2013). You can find the complete work at IEEE Xplore.

Abstract

Digital video has become a very popular media in several contexts, with an ever expanding horizon of applications and uses. Thus, the amount of available video data is growing almost limitless. For this reason, video summarization continues to attract the attention of a wide spectrum of research efforts. In this work we present a novel video summarization technique based on tracking local features among consecutive frames. Our approach operates on the uncompressed domain, and requires only a small set of consecutive frames to perform, thus being able to process the video stream directly and produce results on the fly. We tested our implementation on standard available datasets, and compared the results with the most recent published work in the field. The results achieved show that our proposal produces summarizations that have similar quality than the best published proposals, with the additional advantage of being able to process the stream directly in the uncompressed domain.
