技術說明

本發明係提供一種人工變造生醫實驗影像的檢測系統及方法，用以對輸入影像進行影像檢測。根據本發明之設計，一處理模組、一影像差異運算模組、一二值化模組、與一影像混合模組係透過函式庫、變數或運算元的形式建立於一影像分析裝置之中。同時，本發明又特別設計該處理模組具有一量化參數建立單元、一相似運算單元與一偽背景產生單元，其目的在於影像分析裝置能夠在輸入影像上顯示人造的影像。此外，當量化參數不足或不需進行量化分析時，本發明特別設計該處理模組具有一二維高斯低通濾波單元、一參數設定單元與一偽背景建立單元， 進而讓該處理模組只需利用高斯模糊化的方式完成該輸入影像之影像檢測。 The present invention relates to a forgery detection system and method for biomedical experiment images. The proposed forgery image detection system mainly comprises a processing module, an image difference computing module, a binarization module, and an image mixing module, all of which are integrated in an image analyzing device by means of a library, a set of variables or an arithmetic unit. Meanwhile, the processing module of this invention is specifically implemented by units, such as a quantization parameter establishing unit, a fidelity and smoothness measurement unit,and a pseudo-back ground generating unit, such that the image analyzing device can display and highlight the man-made forgery patterns on the input image. In addition, in cases when the quantization parameters are not given or when the quantitative analysis is not necessary, the processing module of this invention can function according to a backup design consisting of a two-dimensional Gaussian low-pass filtering unit, a parameter setting unit and a pseudo background establishing unit. Based on this backup design, the processing module utilizes Gaussian smoothing to generate a pseudo-background image for accomplishing the forgery image detection procedure.
