Digital forensics has lately become one of the very important applications to identify the characteristics and the originality of the digital devices. This study has focused on analyzing the relationship between digital cameras and the photographs by using the support vector machine (SVM). Based on the fact that the internal imaging formation algorithms of(More)
Recently, digital forensics, which involves the collection and analysis of the origin digital device, has become an important issue. Digital content can play a crucial role in identifying the source device, such as serve as evidence in court. To achieve this goal, we use different texture feature extraction methods such as graylevel co-occurrence matrix(More)

Cryptococcus neoformans pneumonia occurs frequently in immunocompromised patients. The organism is a non-mycelial budding yeast found in the soil and in pigeons droppings. It is rare in immunocompetent patients. The aim of this study was to analyze computed tomography (CT) findings of pulmonary cryptococcosis in both immunocompromised and immunocompetent(More)
Wavelet tree based watermarking algorithms are generally using the energy difference among grouped wavelet coefficients for invisible watermark embedding and extraction. According to the cryptanalysis of wavelet tree quantization (WTQ) scheme, its robustness has been proven weak and modified wavelet tree quantization (MWTQ) is developed consequently.(More)
