Sorry for the bad network (the delay cause the duplicated pages). Do you have any ideas for the question?

Hello, the code is here

cv::Mat src = cv::imread("1.bmp", CV_LOAD_IMAGE_UNCHANGED);
cv::Mat mask = cv::Mat::ones(src.size(), CV_8UC1);
mask.row(10).setTo(255);
mask.col(20).setTo(255); // arbitary shape
cv::Mat roi;
src.copyTo(roi, mask); // get the roi

This is 1.bmp

This is mask

This is roi

If I excute roi = roi + 10, the black parts of roi will also add 10, it's not what I want. How to get a roi without the black parts?

Thanks!

I have found a way to solve this problem. When you have got the mask, just keep it in the memory. After your operation

Thanks for reply. Adding with a mask has solved this problem, but what about other operation? For example, roi.setTo(255

To find the text region in a picture with opencv3.3.1 contrib text example.

File path :" C:\opencv3.3.0\opencv_contrib-master\modules\text\sample\text_recognition_cnn.cpp"

link text

The main function needs the file named "TextBoxes_icdar13.caffemodel", but the file is not in this folder. It's weird! there is only a file named "textbox.prototxt" which may have some connection with it.

Does any body know where can I find the "TextBoxes_icdar13.caffemodel" ？

Thanks !

thanks! It takes me a long time to find the code, thanks a lot!

For text detection, the cpp_file( opencv_contrib/module/text/example/textdetection.cpp) loads "trained_classifierNM1.xml" and "trained_classifierNM2.xml" to create 2 classifer. Does any body know which training set was used to create them?

As far as I know, "trained_classifierNM1.xml" was created by boost with some features, and "trained_classifierNM2.xml" was created by SVM.

thanks in advance!
