Technical analog-digital for segmentation of spectral images acquired with an accousto-optic system

摘要

This paper presents the results of a comparative study of digital segmentation methods and analog methods - digital segmentation. The spectral images were acquired with an acousto-optic system, which allows the acquisition of grayscale pictures in a narrow range of wavelengths. The series of images acquired for the entire visible spectrum, allows simple digital operations, perform segmentation processes. The segmentation is based on the analysis of spectral components over regions of the image. This type of processing is compared with traditional digital processing. The experimental results demonstrate that the segmentation processes developed with the acousto-optical system in conjunction with digital techniques of image processing, reduce the computational cost without compromise the quality of the segmentation.
