Text localization is an important task in text understanding systems. In this paper, an efficient connected component based text localization method is proposed. Two image cues, edge and color, are combined to extract candidate text regions. The non-text regions in these candidate text regions are then removed by the text line information generated from 2D tensor voting. The images in ICDAR 2003 competition...
This paper provides the derivation of speckle reducing anisotropic diffusion (SRAD), anisotropic diffusion method tailored to ultrasonic imaging applications. The conventional anisotropic diffusion is performed in four directions without condition in the previous method. In this paper, a new anisotropic diffusion transform based on directions of edges is proposed. The proposed diffusion is not performed...
Anisotropic diffusion is one of the widely used techniques in the field of image process. Tremendous applications show promising results by using anisotropic diffusion algorithm or its revisions. In conventional anisotropic diffusions, usually 4-neighborhood directions are used: north, south, west and east except diagonal directions of the image. These methods result in the loss of image details and...
