重力边缘检测是一种基于重力定律的边缘检测算法。该算法假设每个图像像素都是一个天体,其质量由其灰度强度表示,它们的相互作用基于牛顿引力定律。本文介绍了该算法的多光谱版本。该方法将引力技术与度量张量相结合,对包括彩色图像在内的多光谱图像进行边缘检测。为了评估该算法的性能,进行了几个实验。实验结果证实了多光谱重力边缘检测的有效性。DOI: http://dx.doi.org/10.11591/telkomnika.v11i7.2808全文:PDF
Gravitational edge detection is one of the new edge detection algorithms that is based on the law of gravity. This algorithm assumes that each image pixel is a celestial body with a mass represented by its grayscale intensity and their interactions are based on the Newtonian laws of gravity. In this article, a multispectral version of the algorithm is introduced. The method uses gravitational techniques in combination with metric tensor to detect edges of multispectral images including color images. To evaluate the performances of the proposed algorithm, several experiments are performed. The experimental results confirm the efficiency of the multispectral gravitational edge detection.
