Introduction Starting this spring 2020 semester at Purdue, I am continuing my capstone course in UAS. Last semester my group began and made great progress in research and experimentation with search and rescue missions aided by UASs. To continue that, we will be doing much more research and analysis this semester, with the goal of writing either a white paper or peer-reviewed publication. Before starting on our literature, we have to answer the question of “what is a white paper?” I’ll be examining that question, analyzing the similarities and differences between a white paper and peer-reviewed literature, and listing pros and cons for each. Finally, I’ll be critiquing a few examples of white papers, and describe how I’ll be moving forward with my writing for the semester. What is a white paper? In short, a white paper is an authoritative document about a complex subject. Purdue’s Online Writing Lab says it is typically used to argue a position or propose a solution to a pr...
Introduction What is Image Annotation? Image annotation is the process of removing unwanted parts of an image from the ray cloud. For example, in the first data set used for this lab we wanted to isolate the truck from the rest of the image. Using image annotation we are able to remove the pavement and other parts of the image to leave just the truck. At what phase in the processing is this performed? Image annotation is performed after the first step, Initial Processing, has been completed, but before the second step has been completed. What types of Image Annotation are there? There are three types of image annotation: Mask, Global Mask, and Carve. Mask annotation would be used for removing an obstacle that appears in a few images, such as scaffolding or tree branches. Global Mask annotation would be used when there is a consistent obstacle between all of the images, such as if the landing gear or propeller from the UAV was in view of the camera lens. Carve...
