Image analysis apparatus using main color and method of controlling the same

A method of controlling an image analysis apparatus, the method comprising:

• receiving a query image;
• determining at least one main color distributed in the query image and a specific main color from among the at least one main color by using color information contained in the query image;
• dividing the query image into at least one block having a predetermined number of pixels;
• determining whether each the at least one block divided from the query image includes more than a predetermined percentage of a first main color among the at least one main color, and creating a binary spatial distribution map by digitizing the at least one block;
• receiving a database image for determining a similarity of the database image to the query image;
• dividing the database image into at least one block having a predetermined number of pixels;
• and
• determining whether each of the at least one block divided from the database image includes more than a predetermined percentage of a second main color among the at least one main color, and creating a binary spatial distribution map for comparison by digitizing the at least one block.

An image analysis apparatus comprising:

• an interface unit for receiving a query image;
• a storage for storing a database image for determining a similarity of the database image to the query image;
• and
• a controller for determining at least one main color distributed in the query image and a specific main color from among the at least one main color by using color information contained in the query image, dividing the query image into at least one block having a predetermined number of pixels, determining whether each of the at least one block divided from the query image includes more than a predetermined percentage of a first main color among the at least one main color;
• and creating a binary spatial distribution map by digitizing the at least one block,
• wherein the controller divides the database image into at least one block having a predetermined number of pixels, determines whether each of the at least one block divided from the database image includes more than a predetermined percentage of a second main color among the at least one main color, and creates a binary spatial distribution map for comparison by digitizing the at least one block.
