ABSTRACT:
The invention provides a method for a motion estimation algorithm. The motion estimation algorithm using low bit resolution integrated edge image instead of luminance image to obtain difference block with small AC coefficients, edge image created by filters is employed to improve encoding quality, on the other hand, operation cost is reduced to low bit resolution. The invention also provides a method for a motion estimation algorithm with a new algorithm using low-bit resolution oriented edge image. Using low-bit resolution oriented edge in motion estimation can result in flatter image blocks which is in demanded by texture-compress unit (such as DCT), as a result, the encoding efficiency is improved, and the operation load is reduced by low-bit resolution.
