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 by workers. The manual inspection of these ID numbers is a labor-intensive task and imposes heavy burden on the workers. In order to overcome these problems...
Non-destructive automatic inspection systems are in high demand in the steel industry, for controlling the quality and increasing the productivity of steel products. In this study, we developed an algorithm for detecting scratch defects on slabs by using image-processing techniques. To reduce the effect of lighting condition and amplify the features of the defects, we used a Gabor filter and carried...
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 general text localization in images actively. Generally, it is known that localizing scene text is more difficult than localizing caption text, and still...
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 treatments are necessary to recognize these texts. In this paper, new optimized text localization and character segmentation algorithms are proposed....
