The need for efficient and accurate processing of DICOM medical images has increased recently due to the distribution systems with diagnosis and treatment planning. The objective of this work is to develop a tool for the clinician and researcher for processing and analyzing DICOM images starting from a series of scintigraphic dynamic renal images. Tracing(More)
Scintigraphic images are often characterized with much noise and a badly contrasted resolution which makes the perception of regions of interest very difficult. The renal quantification is how to define the regions of interests whose activities informs on the status of the renal function. In this context, the current study presents an intelligent system for(More)
The Event detection method from a video surveillance has received much attention in the image processing. In this paper, we present an overview of a new approach for event detection from video surveillance system based on incremental learning. In our approach, each event is modeled by a set of states, and each state is represented by a learning model(More)
Renography is a radionuclide technique introduced in medicine since the early sixties in the daily practice. It allows measuring the function of each kidney separately in case of unilateral or bilateral uro-nephrological disease. A new system for analysis of Renography is presented in this paper. Our system aims to show a fully automated method for drawing(More)
In this paper a new approach to video event detection is presented. This approach is based on HOG/HOF features optimized by an auto-associative neural network models for feature reduction and an incremental SVM model for event classification. This auto-associative neural network models are frequently used to reduce the size of feature vectors. In our(More)
In this paper, we propose, a semi-automatic approach for the identification of Regions Of Interest (ROI) of the kidneys (healthy and diseased) on dynamic scintigraphic images. The triggering of the method depend on the intervention of an expert, such as a specialist in nuclear medicine. Our contribution is made obvious here through referring to the adaptive(More)
