## 3 Experimental Results
### Comparison of Multi-Focus Image (i.e., Flowerpot)  
The evaluation of the eighth multi-focus image is the flowerpot, which is illustrated in Figure 16. Figure 16 represents the original image. Figure 16,c illustrate left-focused and right-focused images, respectively. The term \"left-focused image\" refers to the fact that the image's left side is focused while the right side is not. An image with a right focus indicates that it has been focused on its right side only, while its left side has not been focused on. Figure 16 shows the process of creating the all-in-focus image after the method has been successfully implemented. The following parameters are computed to evaluate the proposed methodology performance: \(Q_{E}\), and _QW_. Finally, the performance of the proposed approach is compared to that of other methods previously published in the literature. The results of the comparison are shown in Table 37 of the report. The letter X indicates that metrics are not calculated for the article depicted in the image. According to the literature [25], the proposed method is more successful than those approaches, and the best outcomes of methods are indicated in bold.
