数字图像(digital image)是指以二维数字组形式表示的图像,是不同亮度或不同颜色组成的矩阵,可以通过数字相机、扫描仪直接获得,或者扫描光学影像的底片经采样量化后获得。 数字图像处理(digital image processing,DIP)是指通过计算机对图像进行去除噪声、增强、复原、变换、分割、提取特征、分类等各种处理的方法和技术,它...
The result of processing the entire image set into spectra following a PCA reconstruction is remarkable and at first hard to believe. The spectra seen in Figure 1 show both the poor signal to noise in the original raw data and thesmootheddata following the PCA and subsequent projection onto th...
Example 1: application of pca in image compression In the field of image processing, PCA serves as a vital tool for image compression, where it helps in reducing the size of image data while retaining essential visual information. By identifying and retaining the principal components that capture...
Project: Application of PCA in Image Processing Using the Yale Faces Dataset Objective: To implement Principal Component Analysis (PCA) on the Yale Faces dataset and evaluate its effectiveness in facial recognition by classifying images based on Euclidean distance and PCA-derived representative images. ...
