Abstract:
A method for performing an inverse telecine process that comprises the steps, performed by a computer system, of:(a) retrieving a current frame and a preceding frame from a source video sequence; (b) determining if the current frame is an original frame by: (i) selecting a first pixel within the current frame; (ii) selecting a first group of one or more pixels in the current frame; (iii) selecting a second group of one or more pixels in the current frame where the pixels included in the second group are located farther from the selected pixel than the pixels included in the first group; and (iv) determining if the similarity between the second group of pixels and the selected pixel exceeds the similarity between the first group of pixels and the selected pixel; (c) adding, where the current frame is an original frame, the current frame to a destination video sequence; (d) determining, where the current frame is not an original frame, if an original frame can be reconstructed; and (e) adding, where an original frame can be reconstructed, a reconstructed frame to the destination video sequence.
