Todo List

Member fl::DescriptorContrast::patch(const Vector< float > &value)

Actually implement this method.

Member fl::ImageFileFormat::getMagic(std::istream &stream, std::string &magic)

Currently there is no guarantee that the stream can actually rewind to the position at the beginning of the magic string. Some streams can go bad at this point because they don't support seekg(). One possibility is to use sputbackc() to return magic to the stream. This could still fail if magic straddles the boundary between buffer loads. Another possibility is to have ImageFileFormat::find() wrap the given stream in a special stream that can always put back at least 16 or so characters regardless of underlying state.

Member fl::KLT::KLT(int windowRadius=3, int searchRadius=15)

Track blobs (as opposed to just corners): The code currently depends on a large determinant in the second moment matrix, which is generally associated with Harris points. Examine whether it is possible to formulate a similar numerical search for blob-like structures. For example, if the determinant of the second moment matrix is negligible, then the first order terms of the Taylor expansion (see papers) is zero, and we can use second order Taylor terms instead. Unfortunately, this would only work for blobs on the same scale as the search window. We may need to code an adaptive window size. Furthermore, this may vary depending on the level in the pyramid.

Member fl::Transform::initialize(const Matrix< double > &A, bool inverse=false)

Store full homography rather than separating into translation and deformation components. The only thing preventing this before was some programs depending on a hack for scaling. No program does this any more.

Member fl::VideoInFileFFMPEG::seekTime(double timestamp)

Seek in c.avi (bear and dog rotating) is screwed up at the FFMPEG level. It has more index than video, and the index seems to be on a different time base than the video itself.
