12:45, 30 May 2023 Mr. MacKenty talk contribs created page Human pose estimation (HPE) (Created page with "Human pose estimation (HPE) is a computer vision task that involves determining the position and orientation of the human body, along with the positions of various body parts such as the head, arms, legs, and so on, usually in real-time. Here's a simplified way to think about it: Imagine you're looking at a photo of a person. You can probably tell what position they're in — maybe they're standing up straight, sitting down, or running. Now imagine trying to teach a com...")
12:44, 30 May 2023 Mr. MacKenty talk contribs created page GPS-denied environment (Created page with "A GPS-denied environment is a location or situation where the Global Positioning System (GPS) signals are not available at all. This can occur for a number of reasons: # Indoor Locations: Buildings often block GPS signals, making them unavailable inside. # Underground or Underwater: Similarly, GPS signals can't penetrate underground or underwater. # Jamming or Spoofing: GPS signals can be intentionally disrupted or blocked using devices known as GPS jammers. Additionall...")
12:41, 30 May 2023 Mr. MacKenty talk contribs created page GPS-degraded environment (Created page with "A GPS-degraded environment refers to any situation or location where the Global Positioning System (GPS) signals are unreliable, weak, or completely unavailable. This could be due to several reasons: 1. **Urban Areas**: In cities with high buildings, GPS signals can become degraded due to the "urban canyon" effect. The tall buildings can block direct signals from the satellites or cause multipath errors, where the signals bounce off multiple buildings before reaching th...")
12:39, 30 May 2023 Mr. MacKenty talk contribs created page Global positioning system (GPS) signal (Created page with "The Global Positioning System (GPS) is a satellite-based navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Here's a simplified explanation of how it works: # The GPS system consists of a network of around 30 satellites orbiting the Earth, controlled by a series of ground stations. These satellites are always transmitting sign...")
12:38, 30 May 2023 Mr. MacKenty talk contribs created page Global map optimization (Created page with "Global map optimization is an important concept in robotics, particularly in the field of simultaneous localization and mapping (SLAM). In essence, it's the process of improving the accuracy and consistency of a map that a robot has created of its environment. Here's how it works: as a robot moves through its environment, it's continually taking sensor measurements and using those to build up a map of the world around it. At the same time, it's using that map to estimat...")
12:36, 30 May 2023 Mr. MacKenty talk contribs created page Edge computing (Created page with "Edge computing is a distributed computing paradigm that brings computation and data storage closer to the sources of data. This is done to improve response times and save bandwidth. The "edge" refers to the edge of a network, closer to the devices that produce or consume data, as opposed to a centralized data center or cloud. Here are the key steps involved in setting up an edge computing environment: # Identify the Need: The first step is to understand why you need ed...")
12:34, 30 May 2023 Mr. MacKenty talk contribs created page Dead reckoning data (Created page with "Dead reckoning is a process used in navigation to determine one's current position based on a previously known position, or fix, and advancing that position based upon known or estimated speeds over a period of time, and the direction in which the person or vehicle is known or estimated to have moved. The name "dead reckoning" comes from "deduced reckoning," sometimes abbreviated as 'ded' reckoning, which has been further abbreviated to "dead" reckoning. In the context...")
12:33, 30 May 2023 Mr. MacKenty talk contribs created page Computer vision (Created page with "Computer vision is a subfield of artificial intelligence and computer science that focuses on enabling computers to understand and interpret the visual world. Essentially, it's about teaching computers to "see" and understand digital images or videos. The way computer vision does this is by taking images or videos, processing them, and then extracting useful information from them. This can involve many different tasks, such as: # Image Recognition: This is one of the m...")
12:31, 30 May 2023 Mr. MacKenty talk contribs created page Bundle adjustment (Created page with "Bundle adjustment is an optimization technique used in computer vision and photogrammetry, which are two fields that are fundamental for the functioning of rescue robots. You can think of rescue robots as needing to understand the world around them, just like you and me. When these robots look at a scene through their sensors, which typically include cameras, they need to determine the 3D positions of objects in the scene, as well as the position and orientation of the...")

The case study is the third paper. Every year, the case study discusses a different topic. Students must become '''very very familiar''' with the case study.

12:46, 1 March 2023 Mr. MacKenty talk contribs created page Just-in-time (JIT) compilation (Created page with "Just-in-time (JIT) compilation is a technique used in computer programming to improve the performance of runtime execution. It involves dynamically compiling code at runtime instead of compiling it ahead of time and storing it in binary form. When a program is executed, the JIT compiler analyzes the code and identifies frequently executed parts of the code. It then compiles those parts into machine code and stores the compiled code in memory, making it available for reu...")
12:45, 1 March 2023 Mr. MacKenty talk contribs created page Transpiling (Created page with "Transpiling (short for "transformation" and "compiling") is the process of converting source code from one programming language to another while maintaining the same functionality. It is a common practice in software development when a developer wants to use modern language features or libraries that are not supported in the target environment. The transpiling process typically involves taking the source code written in the original language and running it through a tra...")
13:58, 3 February 2023 Mr. MacKenty talk contribs created page Stack memory (Created page with "Stack memory is a region of computer memory used for storing da,ta that has a short lifespan such as function call frames, function parameters, and local variables. It operates on a Last-In-First-Out (LIFO) principle, where the most recently added data is the first to be removed. This makes stack memory ideal for storing temporary data and function calls, as the data is automatically cleaned up when the function returns. In a typical computer program, the stack is used...")
