查询词典 fingerprint

In a method and an arrangement for processing a skin print image, and particularly a fingerprint image, which image exists as a gray-level image, provision is made for the gray-level image to be convolved in the direction of two axes by generalized gradient filters, for the generalized gradients obtained in this way to be normalized, for the normalized, generalized gradients each to be convolved with generalized gradient filters, and for the sum of the two results of the convolution of the normalized, generalized gradients to be converted to binary form.

在处理皮肤印迹图像的方法和设备中，具体来说，处理指纹图像的方法和设备中，指纹图像是作为灰度级图像存在的，对于灰度级图像进行如下的规定：通过通用梯度滤波器沿两个轴的方向卷积灰度级图像，归一化以这种方式获得的通用梯度，利用通用梯度滤波器卷积每一个归一化的、通用梯度，并且转换归一化的、通用梯度的卷积的两个结果之和为二进制形式。

Wavelet packet decompresses vibration signals, and wavelet packet nodes which are sensitive to the change of state, as eigen-nodes, form a decomposition tree; the signal restructured at all eigen-nodes can be used as the fingerprint in many breaker diagnostic systems.
