Automatic Contrast enhancement by Histogram Warping
We present an automated algorithm for global contrast enhancement of images with multimodal histograms. To locate modes and valleys, histogram analysis is performed by kernel density estimation, a robust nonparametric statistical method. Histogram warping by monotonic splines pushes the modes apart, spreading them out more evenly across the dynamic range. This technique can assist in the contra...
متن کاملSemi-Automatic Global Contrast Enhancement
Since local contrast enhancement is not sufficient for a detailed visibility of an image, global enhancement also cannot be neglected. Among the global contrast enhancement methods, the automatic enhancement method like Global Histogram Equalization is not always desirable to utilize it for some images that some portions are overexposure and some portions are underexposure and no user's ch...
متن کاملInvertible Data Embedding By Histogram Modification and Contrast Enhancement
The main aim is to enhance the contrast of a host image by Reversible data hiding algorithm and to improve its visual quality. The highest two bins in the histogram are selected for data embedding so that histogram equalization can be performed by repeating the process. The Reversible data hiding algorithm is used for better preserving the visual quality of contrast enhanced image with increase...

متن کاملAutomatic Workflow Generation and Modification by Enterprise Ontologies and Documents
This article presents a novel method and development paradigm that proposes a general template for an enterprise information structure and allows for the automatic generation and modification of enterprise workflows. This dynamically integrated workflow development approach utilises a conceptual ontology of domain processes and tasks, enterprise charts, and enterprise entities. It also suggests...
