Run a python image processing script in an android app
Question: I am using a python script to detect circles using Hough transfrom which
imports "opencv2" and "math" libraries.Can I run this script in an android
app?How can this be done?The following application is the one I want to run in
an android app.`import cv2 import math

    
    
    def resizeImage(img):
        dst=cv2.resize(img,None,fx=1,fy=1,interpolation=cv2.INTER_LINEAR)
        return dst
    img=cv2.imread('20140318_174800.jpg')
    grey=cv2.imread('20140318_174800.jpg',0)
    ret,thresh = cv2.threshold(grey,50,255,cv2.THRESH_BINARY)
    
    circles = cv2.HoughCircles(thresh,cv2.cv.CV_HOUGH_GRADIENT,1,75,param1=50,param2=13,minRadius=0,maxRadius=400)
    for i in circles[0,:]:
        #draw the outer circle
        cv2.circle(img,(i[0],i[1]),i[2],(0,255,0),2)
        #draw the centre of the circle
        cv2.circle(img,(i[0],i[1]),2,(0,0,255),3)
    
    ##Determine co-ordinates for centre of circle
    x1 = circles[0][0][0]
    y1 = circles[0][0][1]
    #x2 = circles[0][1][0]
    #y2 = circles[0][1][1]
    ##Angle betwen two circles
    #theta = math.degrees(math.atan((y2-y1)/(x2-x1)))
    
    ##print information
    print "x1 = ",x1
    print "y1 = ",y1
    #print "x2 = ",x2
    #print "y2 = ",y2
    
    #print theta
    print circles
    
    ##Resize image
    img = resizeImage(img)
    thresh = resizeImage(thresh)
    ##Show Images 
    cv2.imshow("thresh",thresh)
    cv2.imshow("img",img)
    
    cv2.waitKey(0)

Answer: atm, you can't.

you would have to recompile the cv2 module for android first, in a similar way
python4android does it(redirecting system calls to java rmi), tough job.
