“…In order to show the superiority of the proposed optimization method, we compare it with the norm Frobenius (NF) [17], the p-opt [18], i-opt [19] and ideal sinusoidal fringe patterns under the same condition. Figure 1 shows the effectiveness of the proposed method.…”

Background: The recently proposed optimized dithering techniques can improve measurement quality. However, the objective function in these optimization methods just qualifies the global similarity of the pattern while the global optimization methods ignore the influences of local structure. Method: In order to get high quality binary dithered patterns, this paper presents an algorithm which combines optimization on global and local similarity and implements it in the whole-fringe optimization. Results: Both the simulation and experimental results demonstrate that the proposed algorithm can achieve binary fringe patterns with higher phase quality and less intensity difference. The fringe patterns based on the proposed method can get high quality measurement results. Conclusion: The proposed method can get high quality binary dithered patterns under different defocusing levels by combining global similarity and local structure similarity. The proposed method can improve the robustness to the amounts of defocusing.

“…Nowadays, images appear routinely in everyday printed items such as books, magazines, newspapers, fax documents, printer outputs, computer monitor outputs, and LCDs. Likewise, in the current Internet generation, the images do repeatedly arise over web pages and multimedia forms [3]. Besides the Internet, digital storage media such as DVD and CD-ROM do usually accommodate images, pictures, video frames in different formats [4].…”

The objective of the publishing industry is to minimize the number of colors in an image for printing. Also, to retain the better quality from the picture, some useful techniques are needed with the aid of only a few colors. The contouring consequences occur when an image quantized bluntly regardless of the quantization, either uniform or non-uniform. To alleviate the issues of contouring, a slight amount of random noise is added (dithered) to the original image, followed by the quantization method. The methods such as dithering and half toning are extensively used strategies in acquiring texts and pictures in books, newspapers, magazines, computer monitors, and LCDs. This article investigates the dithering technique on a mammogram image with different procedures, such as dithering followed by quantization and dithering, quantization followed by filtering are detailed with Mean Square Error (MSE) and Peak Signal-to-Noise Ratio (PSNR) results. For better visualization, segmentation techniques are applied to the dithering technique.
