python - opencv program data to a excel sheet -


i doing project on image filtering colours using opencv python on osx. have made functioning program when finds object of specific color, prints message in terminal says "found box" , pixel size in frame.

my question when try write data in excel sheet using xlwrt, prints out size of pixel, overwritten in same cell. rather pixel size values appear in column set pixel.

here part of program

  kernel = np.ones((31,31),np.uint8);   opening=cv2.morphologyex(mask,cv2.morph_open,kernel,0);   kernel = np.ones((17,17),np.uint8);   dilation=cv2.dilate(opening,kernel,iterations=2);   opening=cv2.morphologyex(mask,cv2.morph_open,kernel,2);   edges = cv2.canny(mask,100,255)   contours,hierarchy=cv2.findcontours(opening,1,cv2.chain_approx_simple);   res = cv2.bitwise_and(frame,frame, mask= dilation)   #contours=np.zeros(mask.shape,np.uint8);   areas = [cv2.contourarea(c) c in contours]   ar = 0.0   = 0    book = xlwt.workbook(encoding="utf-8")    sheet1 = book.add_sheet("sheet 1", cell_overwrite_ok=false)    sheet1.write(0, 0, "frame")   sheet1.write(0, 1, "pixel")    list1 = [0]    in areas:     print(a);     += 1     ar=float(a)     list1.append(ar)     sheet1.write(i,0,ar)     book.save("/users/canogerardo55/desktop/trial.xls")     if (a>10000):         print("found box");         break;

javascript - three.js lot of meshes optimization -

i'd use three.js render scene containing lot of small meshes create stacks. here's fiddle: http://jsfiddle.net/3bl6fbse/ i'd guys me optimizing code. can see, bit laggy because of low fps. i've written code fast, , m aware creating materials , meshes in loop bad practice. thing need know is: how optimize scene, not doing basic techniques creating materials , meshes outside of loop. i tried use meshes scale's property result ugly, there isn't "stack" effect. tried use mesh.copy ends on same bad performance. thanks

smartface.io - Proper way to change color scheme for whole application -

pls give me hint best way change color scheme whole smartface application: 1. statically (before building project) 2. dynamically (from within running application) if going change scheme 1 time, can change statically. can define new colors, , change old ones in .pge files. but if want change scheme colors more once or while using application, can in runtime dynamically. done in script files. objects properties such fillcolor can changed in scripts. i cannot 1 best changing in runtime looks better. example, can use editbox colors, , can use button, when pressed can change color scheme, etc.
