<p></p> <p><b>新規ページ</b></p><div>== Footage ==<br /> <br /> Use the biggest resolution available for your footage.<br /> <br /> Avoid using footage which underwent lossy compression.<br /> <br /> Since the tracking currently only use luma (grayscale), it won't track well patterns which only have chroma texture.<br /> <br /> Excessive motion blur will affect the accuracy of your track.<br /> <br /> As rolling shutter is not corrected yet, avoid fast motions with slow sensors.<br /> <br /> == Search Window ==<br /> <br /> The search window is the area over which the pattern is searched.<br /> <br /> It needs to be at least as big as the marker relative offset between two frames.<br /> <br /> Reducing search area is a way to track faster.<br /> <br /> == Pattern Window == <br /> <br /> The pattern is the area which is matched between frames.<br /> <br /> On high quality footage (with crisp textures), A small pattern will work best (e.g 16 pixels).<br /> <br /> Big pattern only helps accurately track large or blurry features.<br /> <br /> With unnecessarily large patterns, the tracking will be very slow and fail to track any rotation of the pattern.</div>
