Similarity Threshold	The extent of visual similarity based on which similar images are grouped.视相似性:视相似性的程度，在此基础上对相似图像进行分组。
Preview Resolution	Resolution of the image preview that will be used as the basis for comparison.分辨率的图像预览，将用作比较的基础。
Resolution of Compared Images	Resolution of other image previews that will be compared with the basis.其他图像的分辨率将在预览的基础上进行比较。
Similarity	The minimum percentage of similarity between all selected images.所有选定图像之间的最小相似百分比。

After you click the Refresh button, the comparison process will start. The result of this process will be displayed as the list of groups, each group containing images with a visual similarity exceeding the Similarity Threshold value. Files can be managed via the context menu available by right-clicking on the file in the list.单击 Refresh 按钮后，将启动比较过程。此过程的结果将显示为组列表，每组包含视觉相似性超过 Similarity Threshold 值的图像。通过右键单击列表中的文件，可以通过上下文菜单管理文件。
