Fiji imagej process edge3/16/2024 Allows the option of several different demosaicing algorithms: replication, bilinear interpolation, smooth hue, and adaptive smooth hue. A new stack is created that contains all the frames having a mean value that is at least xx% as high as the highest mean value.ĭebayer Image – Creates a colour image from an input Bayer matrix. The mean values of the edge frames are computed and the frames are ordered according to this value. The edges are computed using the “Find Edges” routine in ImageJ (using a Sobel filter). Select Frames With Best Edges – Selects the frames with the “best” edges from a stack of images. Images that contain a lot of contrast and sharp edges should have a higher quality factor using this method. This is done at three different scales (original size, half size, and quarter size). The factor is computed by taking the sum of the differences of adjacent horizontal and vertical pixels. The output is a listing of the “quality” factor for each image in the stack. Image Quality Calculator – Used for assessing the relative quality of a stack of images. Moon Crater Calculator – Calculates the height of a crater wall or lunar mountain using user input from measurements on lunar images. This results in each image of the stack having the same mean value. Each image is then multiplied by a constant equal to the highest mean/mean of the image. Normalize Values – Measures the mean value of all images in a stack and finds the highest mean. Used to produce sky flat images from a sequence of exposures. (It may be helpful to crop the image so that it just contains the object to be measured.)īackground Extractor – Extracts the background of a stack of images by normalizing each image in a stack and then combining the stack. ![]() Returns the FWHM of the function both in numerical and graphical formats. Plot FWHM – Fits a Gaussian function to a horizontal and vertical cut that is centred on the brightest point in the image. SaveAs FITS – Saves an image in FITS format.
