Detection of Alzheimer’s Disease in Elder People Using Gait Analysis and Kinect Camera
Introduction: Gait analysis through using modern technology for detection of Alzheimer's disease has found special attention by researchers over the last decade. In this study, skeletal data recorded with a Kinect camera, were used to analyze gait for the purpose of detecting Alzheimer's disease in elders. Method: In this applied-developmental experimental study, using a Kinect camera, data wer...

متن کاملFixed Camera Movie Compression Using Pixel State Analysis
従来,監視映像の記録には一定間隔に撮影した画像 フレームを符号化して保存するタイムラプス方式が用 いられている.しかし,タイムラプス方式は監視対象 となる物体が存在しないフレームも保存するため,記 憶量が膨大となる問題がある.一方,オブジェクトベー ス符号化は画像から人物等の重要な前景領域を抽出し, 背景と区別して情報を扱うので映像を高能率圧縮する ことが可能である.本稿では,ピクセル状態分析を用 いたオブジェクトベース符号化について提案する.本 手法は,ピクセル状態分析による物体検出により画像 から前景と背景を判別する.さらに,前景である物体 領域の各ピクセルを静状態もしくは動状態に判別する. 静状態ピクセルは,1フレーム前の同じ位置における輝 度値を配置することにより復元可能であるため,各フ レームにおいて輝度を保存する必要がない.これによ り,記憶量の減少が期待できる.さらに,...
متن کاملValidation of a single camera, spatio-temporal gait analysis system
The measurement of foot-surface contact position would aid the understanding of player movement and step strategy in sports such as tennis. However during competition, it is impracticable to instrument players. A markerless, view-independent, footsurface contact identification (FSCi) system was developed and validated. The FSCi system analysed standard colour video sequences of walking and runn...
