Government intelligence agencies need to continually analyze thousands of images of enemy territory. They are always looking for change - for instance, has the enemy relocated any of its
Measure the radius of a roll of tape, which is partially obscured by the tape dispenser. Utilize imfindcircles to accomplish this task.
Measure the angle and point of intersection between two beams using bwtraceboundary , which is a boundary tracing routine. A common task in machine vision applications is hands-free
Use imfindcircles to automatically detect circles or circular objects in an image. It also shows the use of viscircles to visualize the detected circles.
Calculate the size distribution of snowflakes in an image by using granulometry. Granulometry determines the size distribution of objects in an image without explicitly segmenting
Classify objects based on their roundness using bwboundaries , a boundary tracing routine.
Calculate the length of a pendulum in motion. You can capture images in a time series with the Image Acquisition Toolbox™ and analyze them with the Image Processing Toolbox™.
