Abstract
A method of detecting an ROI is provided. The method includes calculating energy of each of unit blocks constituting an image frame, detecting at least one interest block having energy higher than a threshold value among the unit blocks, forming initial ROIs by dividing the image frame, and removing a medium ROI among the initial ROIs.
Claims20
A method of detecting a region of interest (ROI) comprising:
- calculating energy of each of unit blocks constituting an image frame;
- detecting at least one interest block having energy higher than a threshold value among the unit blocks;
- forming initial ROIs by dividing the image frame;
- and
- removing a medium ROI among the initial ROIs.

A detection device for a region of interest (ROI) comprising:
- an interest block detection unit configured to calculate energy of each of unit blocks of an image frame and to detect at least one interest block having energy higher than a threshold value among the unit blocks;
- and
- an ROI detection unit configured to detect at least one final ROI by dividing the image frame into initial ROIs and removing a medium ROI among the initial ROIs,
- wherein the ROI detection unit configured to remove the medium ROI among the initial ROIs until the number of final ROIs becomes the same as a predetermined number.

A detection device for a region of interest (ROI) comprising:
- an interest block detection unit configured to calculate energy of each of unit blocks of an image frame and to detect at least one interest block having energy higher than a threshold value among the unit blocks;
- and
- an ROI detection unit configured to detect at least one final ROI by dividing the image frame to form initial ROIs having a level n (n≧0, n is an integer) and initial ROIs having a level n+1, and removing a medium ROI among the initial ROIs having the level n+1,
- wherein the level n+1 is the highest level having higher number of the initial ROIs than a number of final ROIs.
