-

i can detect blue color using hough circle, but, need detect 5 color exist , show number of robot. how detect combination using python or opencv? suggestion?

this image:

enter image description here

i don't think need use hough circles, if image size constant per id. here's alternative:

in id image, figure out approx locations of yellowed points shown below:enter image description here

you'll have 5 interest points- (x[0],y[0]) (x[4],y[4])

let's suppose 1 yellow interest point located @ (10,10).

since you're using python, can intensity of interest points using:

 img=imread("id.jpg")#read image     b=[]#declare empty lists     g=[]     r=[]     x=[]     y=[]      #save points of interest___     x[0]=10     y[0]=10 #likewise remaining 4 points      in range(5)         b[i]=img(x[i],y[i],0)#img single id image         g[i]=img(x[i],y[i],1)         r[i]=img(x[i],y[i],2)     if(b[0]==100 , g[0]==0 , r[0]==255)#pinkish colour         print "1st dot pink"

now have total of 15 integers (5 points x 3 colours). can decide unique id based on values.

asp.net mvc - breakpoint on javascript in CSHTML? -

i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
