Anti-aliased DDA

الملخص EN

Bit-mapped images are prone to the jaggies (stair-step effect along edges) because the computer uses small dots to build images.

This effect is called aliasing and the technique used to reduce it is called antialiasing.

This paper investigates aliasing along straight line segments or edges, its origin, and how it is affected by the orientation or slope of the segment.

A method for antialiasing or smoothing the straight line segments by modifying the intensity of the pixels is presented.

Hardware implementation of this method is finally formulated and tested using Field Programmable Gate Arrays (FPGA).
