read_ocv — Reading an OCV tool from file.
read_ocv reads an OCV tool from file. The tool will contain the same information that it contained when saving it with write_ocv. After reading the tool the training can be completed for those patterns which have not been trained so far. Otherwise a pattern comparison can be applied directly by calling do_ocv_simple.
As extension '.ocv' is used. If this extension is not given with the file name it will be added automatically.
Name of the file which has to be read.
Default value: 'test_ocv'
File extension: .ocv
Handle of read OCV tool.
read_ocv("ocv_file",&ocv_handle); for (i=0; i<1000; i++) { grab_image_async(&Image,fg_handle,-1); reduce_domain(Image,ROI,&Pattern); do_ocv_simple(Pattern,ocv_handle,"A", "true","true","false","true",10, &Quality); } close_ocv(ocv_handle);
read_ocv returns 2 (H_MSG_TRUE), if the file is correct. Otherwise, an exception is raised.
