Projection Magnitude
The Edge Locator processes data within the region
of interest along pixel-wide lines, called projection
paths, parallel to the Rectangle's Y-axis. The aver-
age grey-level value for each projection path is
stored in a one-dimensional signal that can be
used in the edge location process.
The Projection Magnitude can range between -
255 and 255. Positive and negative peaks in the
value indicate potential edges. Sharp peaks indi-
cate strong, well-defined edges whereas dull
peaks may indicate noise or poorly-defined edges.
Projection Average
The average grey-level value for all projection
paths within the physical area bounded by the
region of interest. This minimizes variations in
pixel values caused by non-edge features or noise.
