File Histogram matching.PNG thumb 250px An example of histogram matching Histogram matching is a method in image processing of color mapping color adjustment of two images using the imageImagehistogram histograms . It is possible to use histogram matching to balance detector responses as a relative detector calibration technique. It can be used to normalize two images, when the images were acquired at the same local illumination such as shadows over the same location, but by different sensors, atmospheric conditions or global illumination. The algorithm Given two images, the reference and the adjusted images, we compute their histograms. Following, we calculate the Cumulative distribution function cumulative functions of the two images histograms math F 1 , math for the reference image and math F 2 , math for the target image. Then for each gray level math G 1 in 0,255 math , we find the gray level math G 2 , math for which math F 1 G 1 F 2 G 2 , math , and this is the result of histogram matching function math M G 1 G 2 , math .

Adaptive histogram equalization AHE is a computer image processing technique used to improve contrast vision contrast in images. It differs from ordinary histogram equalization in the respect that the adaptive method computes several histogram s, each corresponding to a distinct section of the image, and uses them to redistribute the lightness values of the image. It is therefore suitable for improving the local contrast of an image and bringing out more detail. However, AHE has a tendency to overamplify signal noise noise in relatively homogeneous regions of an image. A variant of adaptive histogram equalization called CLAHE contrast limited adaptive histogram equalization CLAHE prevents this by limiting the amplification. Motivation and explanation of the method Ordinary histogram equalization uses the same transformation derived from the imagehistogram to transform all pixels. This works well when the distribution of pixel values is similar throughout the image. However, when the image contains regions that are significantly lighter or darker than most of the image, the contrast in those regions will not be sufficiently enhanced.

In neurophysiology , peristimulus time histogram and poststimulus time histogram , both abbreviated PSTH or PST histogram , are histogram s of the times at which neurons fire. These histograms are used to visualize the rate and timing of neuronal spike discharges in relation to an external stimulus or event. The peristimulus time histogram is sometimes called perievent time histogram , and post stimulus and peri stimulus are often hyphen ated. The prefix peri, for through, is typically used in the case of periodic stimuli, in which case the PSTH show neuron firing times wrapped to one cycle of the stimulus. The prefix post is used when the PSTH shows the timing of neuron firings in response to a stimulus event or onset. ref cite book title Introduction to Electrophysiological Methods and Instrumentation author Franklin Bretschneider and Jan R.

Unlike other obstacle avoidance algorithms, VFH takes into account the dynamics mechanics dynamics and shape of the robot, and returns steering commands specific to the platform. While considered a local path planner, i.e., not designed for global path optimality, the VFH has been shown to produce near optimal paths.

Dose volume histogram DVH , a concept used in radiation treatment planning ref Drzymala et al. Dose Volume Histograms. Intl J Rad Oncology, Biology and Physics 21, 1991, 71 78 ref . DVHs were introduced by Goitein and Verhey in 1979 in a publication by Shipley et al. ref Phys. Med. Biol. 50 2005 L17 L19 ref . The purpose of a DVH is to summarize 3D dose distributions in a graphical 2D format. In modern radiation therapy, 3D dose distributions are typically created in a computerized treatment planning system based on a 3D reconstruction of a Computed tomography CT scan. The volume referred to in DVH analysis can be a target of radiation treatment, a healthy organ nearby a target, or an arbitrary structure. DVHs can be visualized in either of two ways differential DVHs or cumulative DVHs. A DVH is created by first determining the size of the dose bins of the histogram . Bins can be of arbitrary size, e.g. 0 1 Gy, 1.001 2 Gy, 2.001 3 Gy, etc. In a differential DVH, bar or column height indicates the volume of structure receiving a dose given by the bin. Bin doses are along the horizontal axis, and structure volumes either percent or absolute volumes are on the vertical. The differential DVH takes the appearance of a typical histogram. The cumulative DVH is plotted with bin doses along the horizontal axis, as well. However, the column height of the first bin 0 1 Gy, e.g. represents the volume of structure receiving greater than or equal to that dose. The column height of the second bin 1.001 2 Gy, e.g. represents the volume of structure receiving greater than or equal to that dose, etc. With very fine small bin sizes, the cumulative DVH takes on the appearance of a smooth line graph. The lines always slope and start from top left to bottom right. For a structure receiving a very homogenous dose 100 of the volume receiving exactly 10 Gy for example the cumulative DVH will appear as a horizontal line at the top of the graph, at 100 volume as plotted vertically, with a vertical ... more details
