Vladimir	90be83ae99	Fix an arg for calcHist() in demos `float* histRange = { range };` doesn't make much sense. `histRange` is an array of array(s), so it should have a type of ptr to ptr. Strangely some domos are correct as well as the example for the function https://docs.opencv.org/master/d6/dc7/group__imgproc__hist.html#ga4b2b5fd75503ff9e6844cc4dcdaed35d	3 years ago
float13	1accf3b3f4	Tutorial - Make required input args positional. I think it would help to change all 3 of the the input file arguments to be "positional" for consistency with the other tutorials. This also simplifies the command line input to run this tutorial by reducing typing, and helpfully prints the "usage" info if any of the 3 required inputs are missing. I'm new to OpenCV and working through the tutorials. I kept getting runtime errors with this one until I realized that the arguments weren't positional, and I was missing the "--input1", "--input2, "--input3" flags preceding the filenames. All of the previous tutorials had required filenames as positional arguments and didn't require this. The original code would require each input to be specified like this: ./compareHist_Demo --input1 filename1 --input2 filename2 --input3 filename3 But with this change, the above command is simplified to: ./compareHist_Demo filename1 filename2 filename3 This avoids a confusing runtime error to make things simpler for newcomers like me :)	5 years ago
