AI Technical Summary

Technical Problem

Existing tactile display technologies struggle to effectively process high-resolution color images, making them unsuitable for direct use in low-resolution tactile displays, and lacking adaptation methods.

Method used

By acquiring the filled image, performing edge recognition and contour extraction, generating a line image, and then vectorizing it, a tactile image suitable for low-resolution tactile displays is finally generated.

Benefits of technology

It reduces computational load, improves image processing efficiency, and generates tactile images that are compatible with low-resolution tactile displays, avoiding the problem of poor recognition results caused by direct scaling.
