Alparysoft Deinterlace Filter is developed for elimination of interlace effect, that is caused by connection of two half-frames into one frame, as a result of it the picture looks blurred and striped. Our Deinterlace filter allows to connect half-frames without negative effects. It is useful only if video is intended for viewing on the monitor or getting the single frame, but not for TV. Advantages of the given filter in comparison with analogues: 1) Ability to choose the region of the picture where it is necessary to perform Deinterlace.2) Existing deinterlace filters work with the whole frame, including the places where there was no movement, so there is a loss of information and deterioration of video in these areas. Our filter automatically may determine interlaced places of the frame and carry out filtration only in these places, thus parts of the frame on which there was no movement, remain high quality.3) Many algorithms attempt to interpolate the odd lines by the even lines' points. But when using these techniques odd lines are recreated mathematically, thus the real object may look absolutely different. The techniques of that kind result in losing up to 50% of the initial video information - that is, half of the efforts you made while shooting your video were in vain. We use specially developed motion estimation algorithm. When using this method the frames are restored without losing any original information.4) To speed up the process, the evaluation of movement is conducted in two steps: first the raw, then the fine positioning.5) Our filter works in a real-time mode even on relatively weak computers - and on Athlon XP 1600+ it produces 35 frames per second. Simple methods work faster.
