该函数对整幅图像的背景亮度比较低的时候有效果；当背景亮度变大时，该函数失效(license plate location)

matrix converter is having advantages when compared to traditional converters. the loss are less in this converter.

牛顿法最初由艾萨克·牛顿于1736年在 Method of Fluxions 中公开提出。而事实上方法此时已经由Joseph Raphson于1690年在Analysis Aequationum中提出，与牛顿法相关的章节《流数法》在更早的1671年已经完成了。(Newton' s method originally developed by Isaac Newton in 1736 in the Method of Fluxions openly. In fact this time has been in Analysis Aequationum method proposed by Joseph Raphson in 1690, Newton' s method associated with the chapter " Streams Law" in the earlier 1671 has been completed.)
