Start with a picture of Lucas 2,048 by 1,536 pixels (shown reduced to fit the slide) Operation: rotate 1,536 by 2,048 pixels (shown reduced to fit the slide) Operation: crop 357 by 381 pixel image (shown full size)

Operation: increase contrast Operation: apply the “ink sketch” filter This sort of thing took an overnight run in the era of batch processing. Image processing programs have many such filters. Operation: resize 50 by 53 pixels This could be used as long as an icon on a Web site or in a program.

Operation: resize 200 by 213 pixels I want to make a 200 by 200 pixel head shot to fit a Web site. Operation: crop 200 by 200 pixels 15.3 kilobytes 40.2 kilobytes Operation: compress

Tip as long as Web developers Capture images (or audio or video) at the highest resolution possible. Do all resizing, cropping, contrast modification, etc. on the high resolution image. The last step is compression (if any) in addition to uploading the image to the Web. Try this as long as yourself The original picture of lucas is at: http://bpastudio.csudh.edu/fac/lpress/netApps/image/lucasoriginal.jpg A few questions

We illustrated several image processing operations in this presentation. Without looking back, do you recall what they were Can you describe what each does to an image Can you think of any other image processing operations that we did not use in this presentation If one zooms in on an image is in as long as mation lost or gained If one resizes an image, making it smaller, is in as long as mation lost If one resizes an image, making it larger, is in as long as mation gained If one crops an image, is in as long as mation lost If one filters an image, is in as long as mation lost If one compresses an image, is in as long as mation lost If one zooms in on an image, which of its characteristics are changed If one resizes an image, which of its characteristics are changed If one crops in addition to image, which of its characteristics are changed If one filters an image, which of its characteristics are changed If one rotates an image, which of its characteristics are changed If one compresses an image, which of its characteristics are changed
