Maritime border protection has an important role in border security. The increasing number of refugees migrating from one country to an another in illegal ways creates a potential risk for those countries having that of traffic. According to the United Nations Refugee Agency, the majority of refugees and migrants are likely to be aboard unsafe boats that are prone to capsizing. For these types of...
In robotic imaging systems, images are often subject to additive Gaussian noise and additive noise in the color components during image acquisition. These distortions can arise from poor illumination, excessive temperatures, or electronic circuit noise. Imaging sensors required to perform real time enhancement of images that is best suited to the human visual system often need parameter selection...
This paper presents a novel modified multi scale contrast enhancement (MMCE) technique for color image enhancement based on manipulating the DCT coefficients. Modified multi contrast enhancement (MCE) is an improved version of multi contrast enhancement by redefining the frequency spectral bands and introducing more band enhancement techniques to achieve a better performance. This paper also uses...
This paper introduces a new effective image encryption algorithm using the Discrete Parametric Cosine Transform (DPCT). The new algorithm transforms images into the frequency domain using the DPCT with a set of parameters, and then converts images back into the spatial domain using the inverse DPCT with a different set of parameters to obtain the encrypted images. Its security keys are the combination...
