摘要：Errors in a double-ended motion estimation system are detected. An imagespace is divided into blocks, and a motion vector is derived for each block. The space isalso divided into indication blocks. Each motion vector is used to identify one or more
indication blocks, in which a value is modified. In an example, a backward component ofthe motion vector is used to project a source flag into one indication block, and a forwardcomponent of the motion vector is used to project a destination flag into anotherindication block. After processing each motion vector, an indication block with no flagsset is indicative of pixel data that has not been tracked, and therefore indicative of amotion estimation error. Remedial action may then be taken.
