OpenCV

Currently going through tutorials to use opencv with c++, in the near future will publish a project for a robotics competition All the files are implemented come this website examples: http://opencv-srf.blogspot.com/2010/09/object-detection-using-color-seperation.html

The opencv functions I implemented are :

• Inverting/eroding images
• Video Capture Contrast
• Histogram Equilization
• Object Color Tracking

I made a class for each of the listed functions, if you would like to erode and image follow these steps:

• #include "ErodingFilter.h" in main.cpp header
• call ErodingFilter(); in main.cpp
• change the the cvLoadImage("/Users/kehlinswain/Pictures/FaceShot.png") funciton inside of ErodingFilter.cpp
  • to your specific file name
  • e.g Mat myImage = cvLoadImage("/Users/MyName/Desktop/Favorite.jpg")
• Run the program

If you would like to use the VideoContrast Function follow these steps:

• #include "VideoCaptureContrastChange.h" in main.cpp header
• call VideoCaptureContrastChange(); in main.cpp
• Run the program

If you would like to use the Histogram Equilization Function follow these steps:

• #include "HistogramEquilizationColorImage.h" in main.cpp header
• call HistogramEquilizationColorImage(); in main.cpp
• change to your image location image1 = imread("/Users/kehlinswain/Pictures/FaceShot.png", CV_LOAD_IMAGE_COLOR); inside of the HistogramEquilizationColorImage.cpp file
  • e.g Mat myImage = imread("/Users/MyName/Desktop/Favorite.jpg")
• Run the program

If you would like to use the Histogram Equilization Function follow these steps:

• #include "RedObjectTracking.h" in main.cpp header
• call RedObjectTracking(); in main.cpp
• Currently I have the program set to filter out the black colors, but if you know the HSV values of your color feel free to change it.
• Change the inRange() to the upper and lower bound of your color you want to filter inside of the RedObjectTracking.cpp
• e.g // for black inRange(imgHSV, Scalar(0, 0, 0, 0), Scalar(180, 255, 30, 0), imgThreshold);
• If you use color picker with gimp you can get the exact value of your colors
  • The conversion of GIMP to OpenCv HSV value are:
    • HUE: OpenCV = GIMP/2
    • SATURAION: OpenCV = GIMP/.392
    • VALUE: OpenCV = GIMP/.392
    • LUMA just leave it as zero
• I made a youtube Video to show my results: https://www.youtube.com/watch?v=AJ3ozBzUThk

• The red line tracks whatever color that is thresholded

• Run the program
