Abstract
Image processing to reduce or eliminate jitter when visually highlighting a target capture area of an image capture device such as a smart phone or camera. A method embodiment commences upon receiving a sequence of one or more video frames taken by the image capture device. A routine to identify the largest polygons in the video frames is applied to the sequence. Uncertainty in identification of the largest polygons is reduced or eliminated by applying intra-frame filters to the polygons. Visible jitter that can arise from inter-frame uncertainty when selecting and highlighting target capture areas can be reduced or eliminated by applying inter-frame filters so as to retain selection of a particular target capture area even in the presence of certain capture device movements. A jitter-free representation of the target capture area is visually displayed on a display screen of the image capture device.
