Slide 2

Output Viewer - Idea

• Design program to display output produced by GUI segmentation program

• Use manifest file to find parameter data and extrapolate file names for various parameter specifications

• Allow user to scroll through images in different dimensions, independently

Slide 5

Output Viewer - Limitations

• Limited to 10 parameters (dimensions) – most segmentation algorithms only have 3

• Only one image is displayed at a time• All images must be in same directory and follow

numeric naming convention (produced by segmentation program)

• Manifest File must be included in directory with images

• Manifest File must have proper format

Slide 6

Output Viewer - Possible Improvements

• Could support larger/unlimited number of parameters

• Could display Manifest output data (if present)• Program could hide unused parameter bars• Program could be combined with zoom utility• Needs JPEG support

Slide 7

Zoom Utility - Idea

• Design a program to view, side by side, an image and a small subset of the image, blown up to a much larger scale

• User should be able to change size of zoomed-in section

• User should be able to click the original image to change the position of the zoomed-in section

Zoom Utility - Advantages

• Zoom-box size can be changed (supports values between 10 pixels2 and the minimum of the height and width of the image)

• Supports both JPEG and PPM files (support for other file types can be added)

Slide 10

Zoom Utility - Limitations• Picture box automatically scales image (and causes

blur for small zoom box sizes):

• Program will be reworked to solve this issue

Conclusion

• Output viewer allows picture data to be visualized independently across different dimensions

• Parameter “sweet spots” and “sweet intervals” can be located easily

• Zoom Utility makes viewing image details easy, but needs work
