Designing a Deinterlacing Algorithm

In this task, we need to design an algorithm to convert an interlaced video sequence into a progressive scan format video. The algorithm aims to transform the video's scanning method to better adapt to different playback devices and display screens. This conversion improves video compatibility and quality while ensuring proper playback across various devices. During the algorithm design process, we must consider each frame of the video sequence and apply appropriate processing. This involves rearranging and adjusting pixel data, as well as handling inter-frame relationships in the video. Key implementation aspects include: using spatial filtering techniques like edge-directed interpolation to reconstruct missing lines, temporal filtering methods such as motion-compensated deinterlacing to preserve motion details, and blend functions to merge fields while minimizing artifacts. The ultimate goal is to produce a progressive scan video sequence that can be smoothly played and viewed on any device.
