2. OUTLINE
• How to obtain the exact number of each type
• The formula
• Take type A as example

3. FORMULA TO OBTAIN THE EXACT NUMBER OF
EACH TYPE
• Wimg : width of the image
• Dw : the difference between iterations of width (varies with types)
• Dh : the difference between iterations of height (varies with types)
• {[([(Wimg -3)% Dw] + Wimg -3) * (((Wimg -3 - [(Wimg -3)% Dw])/
Dw )+1 )]/2} *
{[([(Wimg -2)% Dh] + Wimg -2) * (((Wimg -2 - [(Wimg -2)% Dh])/
Dh )+1)]/2}
