Abstract:
1. An image processing method for corner enhancing a digital image received by an image processing system for rendering on an image output device, the method comprising: a) receiving a digital image including a plurality of pixels representing an image to be rendered on the image output device; b) selecting a target pixel among the plurality of pixels; c) defining a plurality of vector windows, each vector window including the target pixel and one or more other pixels about the target pixel, the plurality of vector windows collectively covering substantially all pixels about the target pixel; d) determining the pixel values of each pixel within each vector window: e) determining if the target pixel is an inside corner pixel or an outside corner pixel connected to a corner of the digital image as a function of the pixel values within the vector windows; and f) if step e) determines the target pixel is an inside corner pixel or an outside corner pixel connected to a corner of the digital image, modifying the target pixel to generate a corner enhanced digital image which renders an image with enhanced corners on the image output device relative to the image received by the image processing system, wherein step c) includes: defining a plurality of 1-dimensional vector windows, each vector window including the target pixel and two or more other pixels connected to the target pixel, the plurality of vector windows collectively covering substantially all pixels connected to the target pixel and the plurality of vector windows including a vertical vector window, a horizontal vector window, a first diagonal vector window and a second diagonal vector window, and wherein step e) includes:
