[ B_h, B_w ] = projection_cvip( lab_image, gray_level, normWidth, normHeight )

DESCRIPTION

This functions scales the object with gray_level in the labeled image lab_image to a box of width and height equal to normWidth and normHeight,and then projects the object to each side (x-axis and y-axis) and returns the values in two row vectors B_h and B_w.
