Information processing system, information processing method, information processing apparatus and control method and control program thereof, communication terminal and control method and control program thereof
A technology for recognizing medical items such as medical devices, medical devices, and pharmaceuticals in an image in real time in real time is provided. A medical article and m first local feature amounts each consisting of a feature vector from 1-dimensional to i-dimensional for each of m feature points of an image of the medical article are stored in association with each other and imaged N feature points are extracted from the image in the video, and n second local feature amounts each consisting of feature vectors from the first dimension to the jth dimension are generated. When a small number of dimensions is selected and it is determined that the n second local feature quantities up to the selected dimension number correspond to a predetermined ratio or more of the m first local feature quantities up to the selected dimension number, It is characterized by recognizing that a medical article exists in the image.リアルタイムで映像中の画像内の医療機器や医療器具、医薬品などの医療用物品を認識する技術を提供する。医療用物品と、医療用物品の画像のｍ個の特徴点の、それぞれ１次元からｉ次元までの特徴ベクトルからなるｍ個の第１局所特徴量とを、対応付けて記憶しておき、撮像した映像中の画像からｎ個の特徴点を抽出し、それぞれ１次元からｊ次元までの特徴ベクトルからなるｎ個の第２局所特徴量を生成し、次元数ｉおよび次元数ｊのうち、より少ない次元数を選択し、選択次元数までのｎ個の第２局所特徴量に、選次元数までのｍ個の第１局所特徴量の所定割合以上が対応すると判定した場合に、映像中の画像に医療用物品が存在すると認識することを特徴とする。
