Autor: 桂劲征 Gui Jin-zheng, 苗静 Miao Jing, 丁柏秀 Ding Bai-xiu, 陈宇 Chen Yu, 郑喜凤 Zheng Xi-feng
Publikováno v: Optics and Precision Engineering. 21:1318-1325
An efficient revising method was proposed to revise the display images of a Light Emission Diode(LED) captured by a color CCD camera.Firstly,the uniform standard white board was used to revise the vignetting phenomenon caused by a curved surface of c

Automatic Recognition Technology of Partial Masked Target
Autor: 宋玉龙 Song Yu-long, 王文生 Wang Wensheng, 苗华 Miao Hua, 陈宇 Chen Yu
Publikováno v: ACTA PHOTONICA SINICA. 42:997-1001
The result of target recognition is always influenced by clutter background,low contrast and deficiency luminance of image.Besides the factors mentioned above,detection and recognition of partial masked target has the character of imperfection and in

De-noising algorithm of wavelet threshold for small target detection
Autor: 王文生 Wang Wensheng, 刘柱 Liu Zhu, 陈宇 Chen Yu, 刘希佳 Liu Xi-jia
Publikováno v: Chinese Journal of Optics and Applied Optics. 5:248-256
In order to obtain better de-noising effects and higher Signal-to-noise Ratios(SNRs) for recognizing small targets,the local variance estimation method is adopted to calculate the threshold.Different thresholds are selected for all the high-frequency
