Abstract:
1. A method for deinterlacing an input video sequence, the method comprising: receiving a first pair of fields of a current frame of the input video and a second pair of fields of a reference frame of the input video, the first pair of fields comprising at least one output pixel to be interpolated and the input video being in interlaced format; filtering noise of the received fields of the current frame and the reference frame; detecting one or more edges of the filtered fields of the current frame and the reference frame; spatially interpolating the output pixel based on an edge selected from the detected edges; detecting motion of the output pixel; calculating temporal constraint of the output pixel based on the detected motion of the output pixel, the temporal constraint of the output pixel providing a bound of temporal changes of the output pixel, the calculating temporal constraint of the output pixel further comprises: generating the output pixel in progressive format based on spatial interpolation of the output pixel and temporal interpolation derived from the temporal constraint of the output pixel.
