可以按照倍率缩放,也可以指定分辨率缩放(可能会变形) 原图 0.5倍缩放 private void jBresizeActionPerformed(java.awt.event.ActionEvent evt) { // TODO add your handling code here: System.loadLibrary(Core.NATIVE_LIBRARY_NAME); org.opencv.core.Mat imgMat = imread("src\\resource\\" + jTFimgName.getText());//读取图片 float scale = 0.5f; float width = imgMat.width(); float height = imgMat.height(); org.opencv.core.Mat dst = new Mat(); Imgproc.resize(imgMat, dst, new Size(width * scale, height * scale)); Imgcodecs.imwrite("src\\resource\\0.5.png", dst); } 1.5倍缩放 private void jBresize1ActionPerformed(java.awt.event.ActionEvent evt) { //
