Recently, there has been an increase in the demand for quality control in the steel making industry. This paper proposes a vision-based method for detection of defects in the surfaces of scale-covered steel billets. Scales are formed on the surface o

This paper presents new solutions to recognize template-marked digits in billets. Since these digits can be easily blurred, systematic preprocessing methods and recognition algorithms with better generalization properties are required. In this paper,

Content-based image indexing is to label image based on its content such as color, texture, shape, face, text, and etc. Because the text can be easily localized and recognized compared to other image contents, many researchers have studied about the

In the steel making process, each slab is given unique identification (ID) numbers for their management immediately after the continuous casting. Hundreds of slabs per day are pass through our target production lines and the ID numbers are identified

This paper describes application-oriented text localization and character segmentation in images. Target texts in our application are often damaged by lots of various noise and, as a result, there are many unclear characters. Therefore, some special

In this paper, we present a new detection algorithm for line defects of scale-covered steel billets. Because of the presence of scales on the billet surface, features of surface images such as brightness and textures are non-uniform. To minimize the
This paper suggests a new Affine Projection (AP) algorithm with variable data-reuse factor using the condition number as a decision factor. To reduce computational burden, we adopt a recently reported technique which estimates the condition number of

Periodic torque ripples exist due to non-perfect sinusoidal flux distribution, cogging torque and current measurement errors in permanent magnet synchronous motor (PMSM). These ripples are reflected as periodic oscillations in the motor speed and det
