Join Patrick Royal for an in-depth discussion in this video My solution: Understanding the problem, part of Code Clinic: Java.
- Compared with a computer…the human mind is vastly inferior…in memorization and math skills,…but one area where we do have an advantage…is pattern recognition.…Recognizing that one image is a cropped…version of another is so natural to us…that we usually don't think about what we're doing.…In order to instruct a computer…to check for image subsets…we must specify exactly what we mean…by an image subset and how it can be…applied to the data available.…The first step is to understand how…an image is represented in Java.…
There are two main types of image files,…vector graphics and pixel graphics.…Vector graphics are images where each…element is defined mathematically…as a line, a curve, a polygon,…or some other region.…It is then rendered by the…computer in visual format.…Pixel graphics, where are what we will…be working with, are basically just…large arrays of numbers…where each number represents a certain color…that the computer will display on screen.…Although pixel graphics lose resolution…when they are re-sized…
Patrick introduces challenges and provide an overview of his solutions in Java. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
Visit other courses in the series to see how to solve the exact same challenges in languages like C#, C++, PHP, Python, and Ruby.
