Fast color-brightness-based methods for image segmentation

摘要

Image segmentation utilizing the color and brightness of sections of the image to generate super-pixels is described herein. The image segmentation is implemented pixel-wise. A color triangle is utilized in the classification of the pixels. By using a hierarchical classification table, the memory usage is significantly reduced, and the image segmentation is able to be performed on-the-fly in real-time.

1. A method programmed in a non-transitory memory of a device comprising:
a. acquiring an image using a sensor of the device; and b. performing image segmentation on the image in a color space and brightness space simultaneously, wherein performing image segmentation includes classifying gray-level pixels as belonging to a gray-level category, and subdividing remaining pixels into sub-categories by using a color triangle which is divided into sectors.
