To overcome this problem, multi-frame super-resolution techniques could be used to improve the accuracy. However, most super-resolution techniques assume that a planar object is captured in input images. Therefore, it is difficult to apply them to face images that include non-rigid deformations caused by changes of face poses and expressions. In this report, we propose a multi-frame super-resolution method that can deal with changes of face poses and expressions. To achieve this, alignment of each local region between video frames is performed by using a free-form deformation method. Thus, the proposed method can easily deal with the non-rigid deformation of face images. Experimental results demonstrate that the proposed method improved the performance of super resolution for actual videos. From this, we confirmed the effectiveness of the proposed method.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_10_description_5": {"attribute_name": "内容記述",
