I have loaded the image as gray sclae, I know I need use threshold to binarize it. But how to do it in Java?
Mat imageMat = Imgcodecs.imread(picDir + "color_console.tif",
Imgcodecs.CV_LOAD_IMAGE_GRAYSCALE);
//then what API?

Documentation for threshold function in Java is here. THRESH_BINARY and THRESH_BINARY_INV modes are suitable for binarization.
For example:
Mat binarized;
threshold(imageMat, binarized, 100, 255, THRESH_BINARY);
If result will be unsatisfied, you can try adaptivehreshold function. It performs thresholding more carefully, but it's quite computationally expensive. Documentation for Java is here.
