The identification of brain infarct in computed tomography (CT) images is difficult due the nature appearance of the infarct tissues similar to the normal tissues in the brain CT images. In this paper, a histogram-based colorization method is presented in order to enhance the visualization and interpretation of brain CT images. The presented is aimed to improve the diagnosis of brain CT images,...

The principal component analysis enhances the contrast existing between the different cover types present in an Imagery. A procedure is presented in this paper with regards to the determination of the principal components. The method is tested for a portion of the LANDSAT imagery pertaining to Anantapur region. Another technique, using the concept of non-linear contrast stretching is defined an...

The main aim of image enhancement is to improve the interpretability or perception of information in images for human viewers, or to provide better input for other automated image processing techniques. Many techniques for enhancement of grey scale images such as histogram equalization, contrast stretching etc. can be found in the literature. But those methods are not directly applicable to the...

A method for contrast enhancement is proposed. The algorithm is based on a local and image-dependent exponential correction. The technique aims to correct images that simultaneously present overexposed and underexposed regions. To prevent halo artifacts, the bilateral filter is used as the mask of the exponential correction. Depending on the characteristics of the image (piloted by histogram an...

The aim of image enhancement is to improve the perception of information in images for human viewers, or to provide better input for other automated image processing images. Image Enhancement (IE) transforms images to provide better representation of subtle details. Contrast stretching is an image enhancement technique commonly used for medical images for improving the quality of an image by re...

BACKGROUND Plantar heel pain is a commonly occurring foot complaint. Stretching is frequently utilised as a treatment, yet a systematic review focusing only on its effectiveness has not been published. This review aimed to assess the effectiveness of stretching on pain and function in people with plantar heel pain. METHODS Medline, EMBASE, CINAHL, AMED, and The Cochrane Library were searched ...
