A Vision-based System to Help Senior Citizens for Memory Recall of Object-placing

Human memory ability is gradually degenerated followed by the increasing of age. It is annoying for senior citizens to often forgetting and trying to recall the places of those objects commonly used in their daily lives. This paper presents a preliminary study for developing a vision-based system and helping senior citizens to recall the process of object-placing. In the initial stage, SURF (Speeded Up Robust Features) is adopted to extract feature points from the object image that are further used for the matching to its corresponding video clips in the video database. Experimental results have demonstrated that correct video clips can be retrieved from the database and played for the user to recall after the desired object image is provided. Although impressive results have been achieved, to increase the robustness of this system, more features and objects will be analyzed and used in the future.
