Correlation

The correlation is a measure of association (resemblance) between two images to find those portions that match according to the measure of correlation

Correlation List

Compares the images in list with all the areas of the same dimensions in original image and finds those portions that match according to the measure of correlation.

Window Level Bitmap

Converts a 12 or 16-bit grayscale image to an 8-bit grayscale or a 24-bit RGB image.

Adaptive Contrast

Gives more contrast to regions of low contrast.

Histogram Contrast

Increases or decreases the contrast of the image using its histogram to determine the median brightness as opposed to using an arbitrary value of 128. This function finds the median brightness of the image, then brightens the pixels with values above the median and darkens the pixels with values below the median.

Gamma Correct

Adjusts the intensity of colors in an image by changing the gamma constant that is used to map the intensity values.

Change Contrast

Increases or decreases the contrast of the image.

Change Intensity

Changes the intensity (brightness) of the image.

Change Saturation

Increases or decreases the saturation of colors in an image.

Remap Intensity

Uses a lookup table to change an image's intensity values. You can apply the change to red, green, blue, or all color channels.

Auto Color Level

Applies one of several types of automatic color leveling to an image

Light Control

Controls the light levels of the image.

Balance Colors

Redistributes the RGB values of the specified image, using the values stored in the specified structures.

Change Hue

Changes the hue of colors in an image by rotating the color wheel a specified number of degrees.

Histogram Equalize

Linearizes the number of pixels and enhance the details in an image based on the specified (RGB, YUV, or GRAY) color space by redistributing the colors intensities according to its histogram data.

Change Hue Saturation Intensity

Change the hue, saturation and intensity for all or specified colors in the image

Color Level

Applies color leveling to an image. It changes the image shadows, midtones and highlights

Add Bitmaps

Adds or averages the images in a list.

Add Weighted Bitmaps

Adds or averages the images in a list according to their weight factors, this function minimizes the noise and improves night vision images

Gamma Correct Extended

Adjusts the intensity of colors in an image by changing the gamma constant that is used to map the intensity values. Either of two different color spaces can be specified.

Local Histogram Equalize

Linearizes the number of pixels locally in an image, based on the specified color space. This can be used to bring out the detail in dark areas of an image, and smooth the edges between blocks.

Remap Hue

Uses a lookup table to change an image's hue values.

Adjust Tint

Adjusts the image tint by changing the colors in an image by using two separate color wheel rotations.

Solarize

Applies an effect that mimics the accidental exposure of photographic film to light. It does so by inverting all color data with an intensity value greater than or equal to the threshold that you specify.

Brightness Contrast Intensity

Applies contrast, brightness and intensity adjustments to enhance the image tonal range

Median Filter

Changes the color of each pixel in an image to the median color of pixels in its neighborhood.

Gaussian Filter

Smoothes or blurs an image by applying a Gaussian filter to the specified image.

Smooth Edges

Smoothes the rough edges in the image

Unsharp Mask

Sharpens the specified image by applying the unsharp mask. Unsharpen mask tends to show more details in areas of an image that are normally not visible.

Binary Filter

This filter imposes a binary filter on an image. It performs a user defined effect by using suitable mask.

Dynamic Binary

Binarize an image by using a different threshold value for each pixel of the image

Intensity Detect

Intensity detection is used to threshold an image based on intensity. Thresholding can be helpful in measuring objects such as a tumor in an image.

Auto Binary Segment

Applies binary segmentation to the image using an automatically calculated threshold based on a two-peak method of statistical analysis of the histogram

Get Histogram

Show the color frequencies in the image.

Stretch Intensity

Enhances the image details by increasing the contrast (image levels) in an image by centering, maximizing, and proportioning the range of intensity values according to its histogram values. Unlike ordinary contrast, Stretch Intensity always retains the original number of different intensity values. (Ordinary contrast adjustments can lose values at the high and low ends of the scale.)

Combine

Combines image data from two images (source and destination), letting you specify the areas to be combined, the operations to be performed when combining the data, and which color planes (R or G or B or R, G, and B) are used.

Invert

Inverts the colors in the specified image, making it like a photographic negative.

Math Function

Re-mapping the image colors according to a mathematical function such as square, log, square root, sine and cosine.

Spatial Filter

Imposes a spatial filter on an image. You can supply your own filter or use one of the predefined filters.

User Filter

Apply filtering on the image based on specified user defined mask coefficients.

High Pass

Removes low frequency details in an image, resulting in a sharpened image.

Gray Scale

Converts any image to a gray scale image without changing its resolution.

Get Ferets Diameter

In microscopy, Feret's diameter is the measured distance between parallel lines that are tangent to an object's profile and perpendicular to the ocular scale. Generally, Feret's diameter is the greatest distance possible between any two points along the
