Subject: [PATCH] src/mod/applications/mod_cv/mod_cv.cpp: fix build with opencv

3.4.9

Use cvScalar instead of CV_RGB to avoid the following build failure with
|
opencv 3.4.9:
|
|
mod_cv.cpp:693:24: error: conversion from ‘cv::Scalar {aka cv::Scalar_<double>}’ to non-scalar type ‘CvScalar’ requested
|
CvScalar col = CV_RGB((float)255 * object_neighbors / max_neighbors, 0, 0);
|
^
|
|
Indeed, CV_RGB is defined as cv::Scalar instead of cvScalar since
|
version 3.4.2 and
|
https://github.com/opencv/opencv/commit/7f9253ea0a9fe2635926379420002dbf0c3fce0f
|
|
It should be noted that CV_RGB(r,g,b) = cvScalar(b,g,r,0)
