License Plate Location Based on Symmetry Finding and Color Clustering;

Proposes an image segmentation algorithm based on perceptual color clustering.

In this paper, a color clustering method is introduced to reduce colors and get effective color representation of image sequence.

An Image Retrieval Method Based on Color Statistical Clustering;

In image retrieval,in order to get an integral target object region and reduce background and other objects\' influence to the match,according to the colors of the needed object,multi-color cluster partition was used,and the target region in the searched image was extracted,making the target region contain all the needed object colors.

This paper gives two methods(color mediate method and color classify method),specifies their primary principles and practical method.

These requirements are met in two steps: an off-line color classification based on Maximum Likelihood criterion and real-time color segmentation.

The color classification of wall and floor tiles is the final but important procedure in the whole process.

Firstly, a color classification method was proposed based on the distance between different colors according to the Chinese car license plate color features.
