发明名称 Method and unit for motion detection based on a difference histogram
摘要 Method for motion detection in a current picture (CP) with respect to a reference picture (RP), wherein for a plurality of locations in the current picture (CP) respective difference values (|D|) are determined (B100). A respective difference value is determined based on a difference between a first value and a second value, wherein the first value is descriptive of a photometric measure of one of the locations in the current picture (CP) and the second value is descriptive of the photometric measure of a corresponding location in the reference picture (RP). Based on the difference values, a histogram is determined (B102). The histogram is used as a basis for determining (B104) a threshold (T1, T2, T3). At a respective location in the current picture (CP), motion is detected by comparing the threshold (T1, T2, T3) to the difference value (|D|) of the respective location.
