Due to light absorption and scattering underwater images suffer from low contrast, color distortion, blurred details, uneven illumination, which affect vision tasks research. Therefore, image enhancement is of great significance in applications. In contrast existing methods for specific environments or reliance on paired datasets, this study proposes an multiscene generative adversarial network...

background: volume estimation of brain is important for many neurological applications. it is necessary in measuring brain growth and changes in brain in normal/abnormal patients. thus, accurate brain volume measurement is very important. magnetic resonance imaging (mri) is the method of choice for volume quantification due to excellent levels of image resolution and between-tissue contrast. st...

abstractbackground: delivering the radiation dose to the target volume and minimizing the dose to normal tissues are the main objectives in radiotherapy. the aim of our study is to enhance the contrast of the portal image to increase the accuracy of delineation of the organs in the irradiation field.   methods: the software was written based on local enhancement of the pixel values in image mat...

It is known that many image enhancement methods have a tradeoff between noise suppression and edge enhancement. In this paper, we propose a new technique for image enhancement filtering and explain it in human visual perception theory. It combines kernel regression and local homogeneity and evaluates the restoration performance of smoothing method. First, image is filtered in kernel regression....

Image Enhancement is a commonly used approach for de-blurring the image. In general, image enhancement is to increase the contrast and remove noise so that the processed image is more suitable for special applications. There are two approaches for this – linear and nonlinear. Each method has its own advantages and disadvantages. But studies over the years showed that real applications use both ...

Image Enhancement Is As Much An Art As It Is A Science.” Image enhancement is one of the key issues in high quality pictures such as digital cameras. The main purpose of image enhancement is to bring out detail that is hidden in an image increase contrast in a low contrast image, or to process an image so that result is more suitable than original image. As the Image clarity is very much affect...
