||The recognition result object|
||The index of the recognition starting from zero|
real) The accuracy of the result with the specified index
Returns the accuracy (as a real from 0.00 to 1.00) of the recognized pattern gesture for that recognition result with the specified index.
For example, to get the accuracy of the most similar pattern acording to the recognition results you can
var accuracy = gr_recognition_get_accuracy(result, 0);. To get the second most similar pattern, use 1, and so on.
The index must be between ´0´ and ´gr_recognition_get_number(recognition) - 1´, and they are ordered
by the accuracy.
If you don't specify the index, then the index 0 (the most accurate result) is assumed.
