Image Enhancement for Automated TFT-LCD Inspection System Using Estimation of Intensity Flow Woo-Seob KIM Jong-Hwan OH Chan-Ho HAN Kil-Houm PARK Publication IEICE TRANSACTIONS on Electronics Vol.E90-C No.11 pp.2126-2130 Publication Date: 2007/11/01 Online ISSN: 1745-1353 DOI: 10.1093/ietele/e90-c.11.2126 Print ISSN: 0916-8516 Type of Manuscript: Special Section LETTER (Special Section on Electronic Displays) Category: Keyword: inspection system, TFT-LCD, image pyramid, intensity flow, image enhancement, Full Text: PDF(320.4KB)>>
Summary: We propose a filtering method for optimal estimation of TFT-LCD's surface region except defect's region. To estimate the non-uniform intensity variation on TFT-LCD surface region, the 4-directional Gaussian filter based on image pyramid structure is proposed. The experimental result verified the proposed method's performance | |||||
