SimpleCV side by side view and sift features

Since I'm a beginner to SimpleCV, can somebody please guide me with the following application: The thing is that I'm working on a stereo project. I have two images, from left and right eyes.

  • First: I must display them side by side. (After using features and keypoints drawing it is able to show two images side by side but how can i do this manually?)

  • Second: I will track any mouse click event on any of these images. Then extract the point of click event and mark its location on the other image after a sift detection. (Since left and right views have an intersection, clicked pixel is most likely to be on the other with a little offset/shift). I may use sift features or any other similar method offered in SimpleCV. But by default features use SURF algorithm for detection. How can I switch to sift algorithm and use it? should I create a features object somewhere?

Thanks in advance.

Solution

  • To show two images side by side you can use

    img1.sideBySide(img2)

    For more information about it, start the SimpleCV shell,

    $ simplecv
SimpleCV:1> help(Image.sideBySide)

    This will show you the complete docs of sideBySide function.

    KeyPoints:

    You can use any of the following algorithms for keyPoints.

    • SURF
    • STAR
    • FAST
    • MSER
    • ORB
    • SIFT

    img.findKeyPoints(flavour="SIFT")

    Again for more info, just use help(Image.findKeyPoints) in SimpleCV shell.
