Coding performance evaluation support device, coding performance evaluation support method, and coding performance evaluation support program

摘要

In the coding performance evaluation support apparatus (100), the extraction unit (110) extracts a plurality of motion vectors from the coded video (201). The calculation unit (120) calculates the deflection angles and norms of the plurality of motion vectors extracted by the extraction unit (110). The accumulation unit (140) generates norm data (301) including one norm for each declination angle from the calculation result of the calculation unit (120). The storage unit (140) stores the generated norm data (301) in the memory (105). The output unit (160) outputs information indicating a motion vector search range in the encoded video (201) obtained from the norm data (301) accumulated by the accumulation unit (140).
