Chapter 5: Digital Image Processing

VAB ID #	VAB TITLE	Type of VAB	Description of VAB	Lab Requirements
5.1	Elementary Image Manipulation	Explore and optional building	Take the set of input images and perform the operations discussed in the previous section. Investigate the effect of two strategies for handling negative numbers in images: >Set negative numbers to zero >Ignore the sign and just show magnitude.	Email a summary of each worksheet (7 total) main block functions. List the unique blocks being demonstrated in each worksheet and give a couple of sentences to describe how each block alters an aspect of an image. >How are the blocks manipulating the underlying matrices of the image in order to create these effects?
5.2	Nonlinear Processing of Images	Explore, Design & Build Project	For a set of given images, explore the thresholding operation at different levels. Compare the binary threshold operation where any point exceeding the threshold value is set to 1 and a point below the threshold value is set to 0.	Email a summary of each worksheet's main block functions. List the unique blocks being demonstrated in each worksheet and give a couple of sentences to describe how each block alters an aspect of an image. > How are the blocks manipulating the underlying matrices of the image in order to create these effects?
5.3	Median Filtering for Noise Reduction	Explore	Implement the mean filter operation on images with varying amount of noise. Observe the detailed structure of the output image. Repeat the above experiment for median filter.	Email a summary of each worksheet's main block functions.
5.4	Coin Counter	Design & Build Project	Options: >Change the system to be able to count dimes. >Change the distance of the coins from the camera and make adjustments to count quarters. >Using the bitmapped image with several coin types, be able to identify all coins and correctly total them. >Using the video capture block and spare change, create a real-time coin counter.	Email worksheet with proper annotations and titles to your instructor.
5.5	Sock Matcher	Design & Build Project	Design a worksheet that matches socks.	Explore. The side-by-side sock pictures (bitmaps or .bmp extensions) are in the image directory on your C drive and are identified by number (#10-25).
5.6	Moving Object Tracker	Design & Build Project	Using the image processing block's you'll be assigned from the VAB Image Library, create representative worksheets that clearly illustrate the functionality of these blocks.	Several worksheets will need to be created in order to accomplish this task. Worksheets should point to images in the image directory on your C drive or have new images attached with the final worksheet. image directory > All Image Inventory worksheets must be clearly annotated as to what the blocks functions are doing.
5.7	Motion Tracker Design Project	Design & Build; Formal Report Project	Build a worksheet that can track and create an output when motion is detected. Exact Specifications will be announced.	Formal Lab report. Create a worksheet to implement a device to detect a motion occuring. Email to instructor.
