Nowadays, Radar systems have many applications and radar imaging is one of the most important of these applications. Inverse Synthetic Aperture Radar (ISAR) is used to form an image from moving targets. Conventional methods use Fourier transform to retrieve Doppler information. However, because of maneuvering of the target, the Doppler spectrum becomes time-varying and the image is blurred. Joi...
Noise in an image can affect one’s extraction of information, therefore, denoising is important pre-processing process. Many the existing models have a large number estimated parameters, which increases time complexity model solution and achieved effect less than ideal. As result, this paper, improved image-denoising algorithm proposed based on TV model, effectively solves above problems. The L...
A lot of researchs have been performed in image compression and different methods have been proposed. Each of the existing methods presents different compression rates on various images. By identifing the effective parameters in a compression algorithm and strengthen them in the preprocessing stage, the compression rate of the algorithm can be improved. JPEG is one of the successful compression...
Background and Objective: Body image represents how one perceives his/her body and acts as the most important part of an individual’s image of oneself. It is because a person's physical appearance is the first feature that is judged by people when they encounter each other. On the other hand, a notable measure of mental health is one’s satisfaction with his/her body image and po...
