【Abstract】 The wavelet and the multi-resolution methods were introduced,and used to analysis the image of impress area of the Vickers hardness measurement in the paper.A system was built to detect the edges of the impress in the Martensite material precisely and efficiently by analyzing the sampling signals.The Vickers hardness of materials is analyzed and tested automatically in application of this method.更多还原
