Abstract: PURPOSE: A video encoding method and device and a video decoding method and device using high-speed edge detection are provided to determine a picture partitioning form in advance by using tree structure encoding units through the pre-processing of an input picture, instead of determining a variable-size encoding unit of the picture through a bit-rate/distortion optimizing process. CONSTITUTION: A partitioning form determining part partitions a down-sampled picture into an encoding unit of a predetermined size. The partitioning form determining part determines a partitioning form of the encoding unit by repeating a process of dividing the encoding unit into sub-encoding units according to the existence of an edge pixel in the encoding unit. An image encoding part (12) partitions a picture into tree structure encoding units based on the partitioning form of the encoding unit contained in the down-sampled picture. The image encoding part encodes the picture based on the partitioned tree structure encoding units. [Reference numerals] (11) Preprocessing part; (12) Image encoding part; (13) Output part
