Abstract
Disclosed herein is a method for image preprocessing based on an object of interest. The method includes extracting an object region of interest from an input image, adjusting the object of region of interest, and adjusting a background region excluding the object region of interest.
Claims16
A method for image preprocessing based on an object of interest, comprising:
- extracting an object region of interest from an input image;
- adjusting the object region of interest;
- and
- adjusting a background region excluding the object region of interest,
- wherein the object region of interest is in a form of a segment or a bounding box,
- wherein the object region of interest is extracted in a form of a segment when a height or width of the object region of interest is greater than a first threshold, but is extracted in a form of a bounding box when the height or width of the object region of interest is equal to or less than the first threshold.

A method for image preprocessing based on an object of interest, comprising:
- extracting an object region of interest from an input image;
- adjusting the object region of interest;
- and
- adjusting a background region excluding the object region of interest,
- wherein extracting the object region of interest comprises, when multiple object regions of interest are present, combining the object region of interest with an additional object region of interest within a preset distance therefrom when a height or width of the object region of interest is equal to or less than a third threshold.
2 more elements
An apparatus for image preprocessing based on an object of interest, comprising:
- a processor;
- and
- a memory operably coupled to the processor and storing instructions that, when executed by the processor, cause the apparatus to:
- extract an object region of interest from an input image;
- adjust the object region of interest;
- and
- adjust a background region excluding the object region of interest,
- wherein the object region of interest is in a form of a segment or a bounding box,
- wherein the object region of interest is extracted in a form of a segment when a height or width of the object region of interest is greater than a first threshold, but is extracted in a form of a bounding box when the height or width of the object region of interest is equal to or less than the first threshold.
