Orientation invariant feature detection system and method for unstructured low-quality video

A system operable to detect feature images in video, the system comprising:

• a central processing unit (CPU);
• and
• a storage device coupled to the CPU and having stored there information for configuring the CPU to:
• obtain video frames of images;
• perform a luminance conversion on a first and a second frame of the video frames of images, the second frame being later in time than the first frame;
• perform a motion filter operation on the converted first and second frames;
• perform a chrominance normalization on the second frame;
• perform a color filter operation on the normalized second frame;
• and
• process the first and second frames after the motion filter and color filter operations.

An orientation invariant feature detection system for unstructured low-quality video, the system comprising:

• means for obtaining a first video frame of images and a second video frame of images, the second video frame of images being later in time than the first video frame of images;
• means for performing a luminance conversion on the first video frame of images and the second video frame of images;
• means for performing a motion filter operation on the converted first and second frames of images;
• means for performing a chrominance normalization on the second video frame of images;
• means for performing a color filter operation on the normalized second video frame of images;
• and
• means for processing the first and second frames of video images after the motion filter and color filter operations.
