TL;DR

This paper introduces a color block code technique for image scaling that simplifies annotation graphics, maintains recognition efficiency, and resists scaling and interference, suitable for small objects and low-resolution images.

Contribution

It proposes a novel color block code method combining location and color information for robust image annotation and recognition.

Findings

High anti-scaling and anti-interference performance

Effective in labeling small object surfaces

Applicable to low-resolution images

Abstract

Aiming at the high cost of embedding annotation watermark in a narrow small area and the information distortion caused by the change of annotation watermark image resolution, this paper proposes a color block code technology, which uses location information and color code to form recognizable graphics, which can not only simplify the annotation graphics, but also ensure the recognition efficiency. First, the constituent elements of color block code are designed, and then the coding and decoding method of color block code is proposed. Experiments show that color block code has high anti-scaling and anti-interference, and can be widely used in the labeling of small object surface and low resolution image.
