Abstract
A method for video processing. A first video sequence (VS) is received. The first VS is processed to generate a second VS in a first resolution. The second VS is adjusted to a third VS in a second resolution. It is determined whether the difference between the first VS and the third VS is lower than a predetermined bias level. The second VS is encoded and output if the difference between the first VS and the third VS is lower than the predetermined bias level.
Claims12
A method for video processing, performed by an electronic apparatus, comprising:
- receiving a first video sequence (VS);
- processing the first VS to generate a second VS in a first resolution;
- adjusting the second VS to a third VS in a second resolution;
- determining whether the difference between the first VS and the third VS is lower than a predetermined bias level;
- acquiring statistical features corresponding to the third VS if the difference between the first VS and the third VS is not lower than the predetermined bias level;
- redistributing a bitrate of each frame in the third VS contingent upon the acquired statistical features;
- encoding the first VS to regenerate the second VS contingent upon the redistributed bitrates;
- and
- encoding and outputting the second VS if the difference between the first VS and the third VS is lower than the predetermined bias level.
An apparatus for video encoding comprising:
- a receiving unit;
- an encoding unit coupled to the receiving unit, receiving a first video sequence (VS), processing the first VS to generate a second VS in a first resolution, adjusting the second VS to a third VS in a second resolution;
- and
- an output unit encoding and outputting the second VS if the difference between the first VS and the third VS is lower than the predetermined bias level, wherein if the difference between the first VS and the third VS is not lower than the predetermined bias level, acquiring statistical features corresponding to the third VS, redistributing a bitrate of each frame in the third VS contingent upon the acquired statistical features, the encoding unit encodes the first VS to regenerate the second VS contingent upon the redistributed bitrates.
