Analysis of motion (motion estimation for coding, decoding, compressing or decompressing digital video signals H04N19/43, H04N19/51)

Introduced: January 1995

Title

Titles differ between systems:

IPC: Analysis of motion

CPC: Analysis of motion (motion estimation for coding, decoding, compressing or decompressing digital video signals H04N19/43, H04N19/51)

Full Title

Full titles differ between systems:

IPC:

Image analysis > Analysis of motion

CPC:

Image analysis > Analysis of motion (motion estimation for coding, decoding, compressing or decompressing digital video signals H04N19/43, H04N19/51)

IPC and CPC are identically structured here. All 10 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 2017.
