The similarity of the element of matrix after DCT is studied by theory with changing of brightness or contrast, and with transformation of mirroring or transposing.

从理论上研究了图像在发生亮度和对比度变化、镜像或转置变化时，其DCT变换后的矩阵元素之间具有相似性。

A two-times locating method based on the gray contrast of surroundings is presented in locating central reference point. This method has better adaptability and robustness, and can basically meet for the accuracy of automatic locating center. Fourier spectral analysis is improved to obtain a more accurate ridge frequency in computing ridge frequency. The average ridge width is used in designing Gabor filters, so the filters have certain adjustability. The rotating invariance of fingerprint images is solved by the rotating of feature models in feature matching.

在中心参考点定位部分，提出了基于局部邻域灰度对比度的二次定位方法，该方法具有较强的适应性和鲁棒性，基本满足自动中心定位的准确度要求；在频率域估计中，改进了傅立叶谱分析法，提高了纹线频率计算的准确度；引入平均纹线宽度作为Gabor滤波器的设计参数，使滤波器具有一定的自适应性；在特征匹配阶段，通过对特征模板的旋转解决指纹图像的旋转不变性问题。

Second, the asphalt mixture digital image processing technique was developed, and the main goal is to improve the image quality especially to improve the gray scale and the contrast between the aggregate particles and asphalt mastic.

初步开发了以提高图像质量，特别是集料颗粒与沥青砂胶之间的灰度对比度为主要目的的沥青混合料数字图像处理技术。
