Summary:To provide an image processing device, an image processing method, and a computer program that can maintain analysis accuracy over the entire image even when image quality deteriorates partially.SOLUTION: In an image processing device, an image analysis device includes: an input image acquisition unit that acquires an input image; an image dividing unit that divides the input image to generate a plurality of partial images; a feature amount estimation unit that estimates a feature amount for each of the partial images; a deterioration degree estimation unit that estimates a deterioration degree for each of the partial images; and a density estimation unit that estimates a density of an object for each of the partial images based on at least the feature amount and the deterioration degree.SELECTED DRAWING: Figure 2 【課題】部分的に画質が劣化する場合でも、画像全体にわたって解析精度を維持できる画像処理装置、画像処理方法及びコンピュータプログラムを提供する。【解決手段】画像処理装置において、画像解析装置は、入力画像を取得する入力画像取得部と、前記入力画像を分割して複数の部分画像を生成する画像分割部と、前記部分画像の夫々について特徴量を推定する特徴量推定部と、前記部分画像の夫々について劣化度を推定する劣化度推定部と、少なくとも前記特徴量と前記劣化度に基づき前記部分画像の夫々について対象物の密度を推定する密度推定部と、を備える。【選択図】図２
