摘要
Abstract
In order to solve the problem of glisten and noise, a six-step pretreatment method was proposed in this paper. To solve the problem of glisten, area of glisten should be confirmed by threshold selecting. Then glisten area was filled by pixel of background. And then dial scale was resumed by character interpolation. Guassian filter and median filter were used in wipping off Guass noise and salt-pepper noise. Laplace sharping was used in improving edges and details. Experimental results show that six-step pretreatment method can decrease glisten and noise in image of pointer instrument. Six -step pretreatment proposed a new idea for pretreatment of image of pointer instrument, and it has some referenced value. 关键词
