Image Threshold

Students will use threshold processing to detect roads in an image

In this lab, students will use an image thresholding technique to segment an image to two categories, foreground and background, with the goal of detecting roads. Students will experiment the effectiveness of different thresholds and troubleshoot varying lighting conditions. The lab includes both background information regarding image thresholding and in-lab exercises.
