图像缩小 meaning in Chinese
image reduction
Examples
- The changing from data file of 3ds max to file of opengl is emphasized in the article . the texture mapping theory is another keystone of the discourse . apply the theory to 3d textile rendering and perfect it with mipmapping and texture interpolation can get a good result
文中详细论述了opengl纹理映射技术的原理及其在三维演示效果中的应用，并采用了多级纹理细化技术对映射效果进行改善，从一定程度上减少了由数字图像缩小和拉伸引起的纹理失真。 - Fourth , the wavelet filter banks is constructed and the two - dimensional separable wavelet transform of the image is realized by the wavelet filter banks . fifth the grads image of manufacture kit is gained on the base of wavelet transform and then image edge can be detected with the use of grads module of image . in the end , the inflection points of image edge can be detected with the use of one - dimensional wavelet transform and the recognition of the manufacture kit can be realized by the relation of the inflection points
另外，为了增强处理的实时性，将灰度图像缩小；第三步，为了减轻光线不均匀对灰度图像造成的影响，对产品图像进行灰度直方图均衡；第四步，构造小波滤波器组，并利用小波滤波器组对产品图像实现二维可分离小波变换；第五步，在小波变换的基础上得到套件产品的梯度图像，然后根据图像梯度模值的极大值提取图像边沿；最后，用一维小波变换提取图像边沿上的犄角点，并利用犄角点之间的联系实现对套件产品的识别。
