Au Mexique, les photographies de victimes du crime organisé font quotidiennement la une des journaux dits nota roja. Leur irruption massive à fin XXe siècle bouleverse le sens et fonction images morts, qui appartiennent longue tradition iconographique. Surexposant cadavres, banalisant traitement dégradant leur est infligé, morts sont dès lors dépouillées significations sociale qu’elles assuraie...

Consumers’ prior experiences shape an episodic memory which largely influences their decision-making process. This episodic memory is mainly linked to cognitive and emotional perception and we know that a brand image influences our cognitive and emotional perception. Nevertheless, it has not been well described how autobiographical memories of brand images differ from those of other types of im...

introduction: spect is a diagnostic imaging technique the main disadvantage of which is the existence of poisson noise. so far, different methods have been used by scientists to improve spect images. the wavelet transform is a new method for de-noising which is widely used for noise reduction and quality enhancement of images. the purpose of this paper is evaluation of noise reduction in spect ...

introduction: in this study the evaluation of a platelet-based maximum penalized likelihood estimation (mple) for denoising spect images was performed and compared with other denoising methods such as wavelets or butterworth filtration. platelet-based mple factorization as a multiscale decomposition approach has been already proposed for better edges and surfaces representation due to poisson n...

conclusion various filters are needed to improve the image quality. in this study, seven different filters were implemented and investigated on both noisy and noise-free images. background developmental dysplasia of the hip (ddh) can be detected with ultrasonography (usg) images. however, the accuracy of this method is dependent on the skill of the radiologist. radiologists measure the hip join...

the fusion of medical images is very useful for clinical application. generally, the pet image indicates the function of tissue and the mri image shows the anatomy of tissue. in this article we fused mri and pet images and the purpose is adding structural information from mri to pet image. the images decomposed with curvelet transform, and then two images fused with applying fusion rules. we us...

as the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. this processing comprises two fundamental and critical steps towar...
