CS 223B Project: Color Edge Detection Examples
We executed imgCED and imgCanny on several images.
The results are below.
There are five sets of examples. Each set contains six different
images. The first two are the ppm and pgm (created from the ppm) of
the original image. The second two are the PGM and PBM images created
by executing imgCED on the original image (before and after
the edge synthesis step). The final two are the PGM and PBM resulting
from running imgCanny on the original image. The last link,
.csh, is the script used to produce the above images.
In addition to the original pnm images, jpg's and gif's were created
for ease of viewing.
The prague image was taken with a film-based camera, scanned, saved as
a tiff, converted to jpeg, then converted to ppm. It is thus
pre-smoothed because of the jpeg conversion.
Squares was automatically generated and designed to have a constant
grey-scale intensity. The c file used to generate squares is also
Lena was a tiff procured from an image database on the web.
Fruit and blocks were supplied by
Koschan of Technische Universität Berlin and were used in
his color edge detection algorithm tests.
