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...")

21:49, 5 February 2023 Bmackenty talk contribs created page Vector (Created page with "In computer science, a vector is a data structure that represents an ordered, dynamic array of elements. It's similar to an array, but it has the advantage of being able to dynamically resize its size as elements are added or removed. A vector typically stores elements of the same data type, and provides operations to add, remove, or access elements. The size of a vector can change as elements are inserted or deleted, and it automatically reallocates memory as needed. T...")
21:32, 5 February 2023 Bmackenty talk contribs created page Unsigned integers (Created page with "Unsigned integers are a type of integer data type that can only represent non-negative whole numbers (positive numbers and zero). They are represented using a fixed number of bits, typically 8, 16, 32, or 64 bits, depending on the computer architecture and the programming language. Unlike signed integers, unsigned integers do not use a sign bit to indicate the sign of the integer value. Instead, all bits are used to represent the magnitude of the integer value. This all...")
21:31, 5 February 2023 Bmackenty talk contribs created page Signed integers (Created page with "Signed integers are a type of integer data type that can represent both positive and negative whole numbers. They are represented using a fixed number of bits, typically 8, 16, 32, or 64 bits, depending on the computer architecture and the programming language. The most significant bit (MSB) is used to indicate the sign of the integer value, with a value of 0 representing a positive number and a value of 1 representing a negative number. The remaining bits are used to r...")
21:28, 5 February 2023 Bmackenty talk contribs created page Scalar type (Created page with "Scalar type in programming refers to a data type that can represent a single value, as opposed to a more complex data structure such as an array or object. Scalar types can include primitive data types such as integers, floating-point numbers, and strings, among others. In many programming languages, scalar types are also referred to as simple or atomic data types. A scalar type is a general term used to describe a data type that can represent a single value. A primitiv...")
10:11, 4 February 2023 Bmackenty talk contribs created page Struct (Created page with "A "struct" is a composite data type that groups together zero or more values with different data types into a single unit. It is used to represent a single object made up of multiple pieces of data, such as a point in 2D space (x, y), or a record in a database (name, address, age, etc.). Each piece of data within a struct is called a "field". Structs can be found in many programming languages, including C, C++, and Rust. They provide a way to bundle related data into a s...")
10:07, 4 February 2023 Bmackenty talk contribs created page Enum (Created page with "An "enum" (short for "enumerated type") is a data type that consists of a set of named values. It is used to represent a set of distinct, named values in a program, making it easier to read, maintain, and avoid bugs. For example, in a program that tracks the days of the week, an enum could be used to represent the days of the week instead of using raw integers or strings. Enums can be found in many programming languages, including Rust, C++, and C#.<ref>ChatGPT</ref> I...")
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...")
13:57, 3 February 2023 Mr. MacKenty talk contribs created page Heap memory (Created page with "Heap memory is a region of computer memory used for dynamic allocation of objects at runtime. It is a dynamic area of memory where blocks of memory are allocated and deallocated dynamically as needed, in contrast to the stack memory, where memory is allocated and deallocated in a last-in-first-out (LIFO) manner. Objects stored in the heap have a longer lifetime than objects stored in the stack, as heap-allocated objects persist until they are explicitly deallocated or un...")
10:40, 29 January 2023 Bmackenty talk contribs created page Binary classification model (Created page with "A binary classification model is a type of machine learning model that is used to classify data into two distinct classes or categories. These models are trained to differentiate between two possible outcomes, such as "yes" and "no", "true" and "false", or "positive" and "negative".
