When working with digital image files, it is essential to know the differences between each one, so you know when to use them. The main difference between files formats is how they are used when designing for the web and the outcome they produce. One produces highly optimized simple graphics, another is used for most images, and the third option is used for complex graphics, gradients and transparency.. and Signifying Practices 199715 The reflective approach asks if language merely reflects meaning that already exists in the world The intentional approach seeks to find if the meaning expresses onl and Image Processing. Computer imaging can be separated into two primary categories:. 1. Computer Vision.. 2. Image Processing. In computer vision application the processed images output for use by a computer.
