Content aware video resizing

摘要

Content aware video resizing is described. In one example, edge detection is done on pixel values of video frames. The edges are compared and an energy is determined for lines of pixels of a second frame based on the comparison. The low energy lines are selected, and the frame is resized using the selected lines. The lines correspond to either rows or columns and the resizing may be done by adding or removing columns or by adding or removing rows.

1. A method comprising:
capturing a first and second frame of a video sequence, the frames having pixel values in rows and columns; detecting edges of pixel values of the first and second frames; comparing the edges of the first frame with the edges of the second frame; determining an energy of lines of pixels of the second frame based on the comparison, the lines corresponding to either rows or columns; adjusting the determined energy by reducing the energy of each line that was selected in the first frame by a weighting factor; selecting lines having the lowest energy; and resizing the second frame using the selected lines having a low determined energy.
