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;

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.

javascript - IE11 incompatibility with jQuery's 'readonly'? -

the code i'm running has no issues in firefox, or chrome. user typing 1 textbox, tabs next , can continue typing that. when run webpage on ie11, user tabs next textbox , can't type in. textbox has double-clicked before user can insert anything. i've googled , seems ie give problems when using older jquery (i.e. prefers 'prop' 'attr' ). in code below jquery's readonly keyword being used in way ie11 no longer recognise/accept? i assume issue readonly , removeclass('ignore') working expected. //when focus on textbox 1 $("#field1").focus(function() { //remove readonly property textbox 1 $('#field1').prop('readonly', false).removeclass('ignore'); //add readonly property other textboxes $('#field2, #field3, #field4') .prop('readonly', 'readonly').addclass('ignore').val(''); }); i'm using jquery 2.1.3 ...
