cmvision - Fast color blob detector

cmvision port for ROS Noetic. Tested on Ubuntu 20.04

Dependancies

WxWidgets

    apt install --no-install-recommends -y \
    libgtk-3-dev  \
    wx3.0-headers \
    libwxgtk3.0-gtk3-dev
    

Usage

Use colorgui node to select the color ranges for your blobs (Sample launch file in launch/colorgui.launch)
- Click on the colors you want as the images play on the window. The AB range will get updated with the each click. Use this range in the colors file (Sample file in config/colors.txt)
Use cmvision node for blob detection (Sample launch file in launch/cmvision.launch)
- Pass the colors file with param cmvision/color_file
- Set param cmvision/debug_on to true to display the detections

TODO

Remove WxWidgets dependancy and use OpenCV highgui for colorgui
Publish debug image to a rostopic with a new param to enable it
Remove the need for the spaces being exactly correctly for specifying colors in colors.txt
