Abstract

The invention provides a digital image classification method. Firstly, the method executes a discrete cosine transform aiming at a candidate region of a digital image for producing a group of discrete cosine transform coefficients. Then, the method produces a group of texture parameters according to the group of discrete cosine transform coefficients. Finally, the method produces a classificationresult of the digital image according to the group of texture parameters.

Description

technical field

[0001] The present invention relates to image classification, and in particular to a digital image classification method and a classification device. Background technique

[0002] In recent years, due to the continuous innovation and advancement of image technology, the digital image market has also flourished. Most of the photos nowadays have been taken digitally (for example, with a digital camera) and stored in a digital format (for example, stored in a memory card, CD or hard disk).

[0003] Generally speaking, after taking a large number of digital images, users will store these digital images in a memory card, transfer them to the hard disk of a personal computer, or burn them into photo CDs. Over time, the number and types of digital images stored in various forms of storage devices are bound to increase. At this point, if not properly managed and categorized, these digital images will appear quite messy and disorderly. Especially when the user is l...
