Accuracy Evaluation on Area Measurement using Pseudorandom Pixel Placement for Low Resolution Images

Conventional imaging systems have the pixels that are arranged in the regular lattice positions, or lattice pixel placement (LPP). LPP is employed in most imaging systems for its advantages on pixel read-out and image reconstruction ways, however, in LPP, the clarity on image representation depends on the direction of the object in the image, or the directional dependency exists. In this paper, we propose the pseudorandom pixel placement (PPP) for reducing the directional dependency on the accuracy in the area measurement. We carried out the simulation to evaluate the directional dependency decrease effect for various pixel parameters, and discuss the optimum pixel parameters and the image resolution.
