This option is useful after you have selected several ROIs. Show the originally selected area for the ROI in the current image. Plot, and as shown later, classification areas based on this spectrum. Open a color picker dialog to change the label color of the spectral Some of the most used options are listedĬhange the name and save the spectrum as a file. Right-clicking on the spectrum in the resource tree or selecting Spectrum from the menu bar will reveal a menu of options. Selecting Mean Spectrum creates a new entry in the resource tree The pan tool will allow you to pan within the spectral plotter as well. Alternatively, click on the magnify tool, then click or drag in the spectral plotter to zoom in. To examine the plots in more detail, you may resize the plot panel boundary by dragging the edges.
You can also set the range of the plot by selecting Selecting it, selecting a rectangular region in the plot window, right clicking to bring up the menu, and selectingĬrop spectrum. Individual spectra can be selected by clicking on the graph of the spectra. Show or hide the standard deviation envelope with the Standard deviation can be shownĪs an envelope around the spectrum plot. Selected and plots the result in the spectral plotter. Option calculates the mean spectrum of all the pixels within the ROI area you
The other ROI options can be found in Basic Data Acquisition.) Selecting the mean spectrum One of the most useful selection options is mean spectrum. Selection tools, holding control while using the floodfill tool will allow a selection to be built up throughĪn ROI consisting of multiple parts of the image has been selected by using the floodfill tool several times. it allows pixels that are less similar to the clicked pixel to be included in the selection).ĭecreasing the tolerance will result in smaller selected regions with greater spectral similarity. Increasing the tolerance will result in a larger selected region with greater spectral variability Selected area contains all of the contiguous pixels for which the spectral distance to the clicked pixel is less than the Or SAM angle in spectral space between the clicked pixel and all contiguous pixels and expands the selection until the The use of the floodfill tool depends on an adjustable tolerance parameter.įloodfill operates on a representation of the datacube scaled from zero to one in each band.
The Workbench tab from File ‣ Preferences menu. The user can set these options by accessing With either Euclidean distance or Spectral Angle Mapper (SAM), along with a tolerance value. The floodfill tool shows pixels that are spectrally similar to the chosen pixel. Apply parental control to dangerous topics and keep your children's integrity and the security of your Internet connection.The selection menu is also available in the main menu. There are preset prevention levels based on the age of the children, and you have access to the activity reports.Ĭontrol Internet content that is ill-suited for children by downloading K9 Web Protection for free.
