my program is :

please do not use outdated c-api code like that any more.

throw it away entirely, start again with the objdetect tutorial and report back ...

please berak tell me how to fix Error loading face cascade Error loading eyes cascade

the error means, that those cascade files were not found, you will hat to correct the path to those xml files (try with an absolute path first., and use "/" , not "\" as seperator)

btw, do you see the difference between the c and the c++ version now ?

i tried :

String face_cascade_name = "/path/to/the/haarcascade_frontalface_alt.xml"; String eyes_cascade_name = "/path/to/the/haarcascade_eye_tree_eyeglasses.xml"; and : String face_cascade_name = "C:Users\Acer\Documents\Visual Studio 2015\Projects\opencv\haarcascade_frontalface_alt.xml"; String eyes_cascade_name = "C:Users\Acer\Documents\Visual Studio 2015\Projects\opencv\haarcascade_eye_tree_eyeglasses.xml";

and no result the same error :/

skander gravatar imageskander ( 2016-01-21 10:05:02 -0500 )edit

either: String face_cascade_name = "C:Users/Acer/Documents/Visual Studio 2015/Projects/opencv/haarcascade_frontalface_alt.xml"; or String face_cascade_name = "C:Users\\Acer\\Documents\\Visual Studio 2015\\Projects\\opencv\\haarcascade_frontalface_alt.xml";
