PS0 Solution by Ivan Brusic

Input Image	Operations	Output Image
capture.rgb (saved using capture from SGI)	Converted to TIFF using imgworks on SGI
	Convert to grayscale img = imread('ivan.tif'); gray_img = rgb2gray(img); imshow(gray_img);
	Interactive crop img_crop = imcrop(img_gray); imshow(img_crop);
	Edge Detection img_edge = edge(img_crop,'log'); imshow(img_edge);

Other edge detection images:

Operations

Output Image

Same as above

Convert to a binary image

[img_bin,map]= gray2ind(img_crop,2);

imshow(img_bin,map);

Edge Detection

img_edge = edge(img_crop,'log');

imshow(img_edge);

Same as above

Convert to a binary image using specified threshold

image = threshold(img_crop,0,100);

imshow(image);

Edge Detection

img_edge = edge(img_crop,'log');

imshow(img_edge);

Output Image

Same as above

Futuristic Ivan

imshow(img_crop);
colormap(cool);

Same as above

Ivan on Drugs

img_rotate = imrotate(img_crop,90,'bilinear','crop');

imshow(img_rotate);
colormap(colorcube);

Note: all TIFF were converted to GIF images for displaying purposes. This process was done using ImageWorks on SGI.
