We demonstrate that gaps and distributional patterns embedded within real-valued measurements are inseparable biological and mechanistic information contents of the system. Such patterns are discovered through data-driven possibly gapped histogram, which further leads to the geometry-based analysis of histogram (ANOHT). Constructing a possibly gapped histogram is a complex problem of statistica...

This paper presents a novel approach called Spread Histogram for calculation of spatial relations between objects. It allows to determine such relations as INSIDE, OUTSIDE, ENCOMPASS. Additionally, the method cooperates very well with standard histogram methods like Histogram of Angles for determining the directional spatial relations.

Due to the uncertain, diverse, and light-attenuating characteristics of underwater environment, images have low contrast unclear problems. This paper proposes a histogram equalization algorithm based on optimized adaptive image quadruple segmentation cropping (AQSCHE). Compared with traditional enhancement algorithm, this introduces technology. Using exposure value point calculation formula tha...

Traditional histogram enhancement algorithm to enhance image has the defect of over-bright image, amplified noise, and missing image details. In view of these defects, this paper proposes an image enhancement algorithm based on second generation wavelet integer transform. At first, use the second generation wavelet integer transform to decompose the original image with wavelet. Then, integer lo...

A histogram-based technique for robust contrast measurement is proposed. The method is based on fitting the histogram of the measured image to the histogram of a model function, and it can be used for contrast determination in fringe patterns. Simulated and experimental results are presented.

This paper proposes the use of a vector of color histogram peaks as an efficient and effective way for many image indexing problems. It shows that histogram peaks are more stable than general histogram bins when there are variation of scale and/or scale. We also introduce the structure of a room recognition system which applies this indexing technique to omni-directional images of rooms. Experi...

Integral Histogram is widely used among various real-time algorithms due to its computationally efficient facility to compute histograms from an image. However, its advantage is greatly diminished for algorithms requiring only a few histograms since required initialization operation takes up majority of total running time. In this paper we propose a block-based integral histogram that drastical...

-------------------------------------------------------ABSTRACT ------------------------------------------------------------Image Enhancement aims at improving the visual quality of input image for a particular area. The criterion used by enhancement algorithms to enhance the image is; using histogram details of that image. This paper defines the various applications of histograms through which...

This paper deals with some error effects caused by additive noise at analogue-to-digital converters (ADCs) testing based on the histogram method and the exponential shape of input testing stimulus. The histogram method with the exponential stimulus has been an alternative test method for ADC that was developed by the authors of this paper. Here, the theoretical analysis of some errors in estima...
