Screen Shot and Video:
Description:

  • Purpose
    This app is capable of identifying the objects on image, together of measuring their characterics.
  • Installation
    Download the file "Image Object Counter.opx", and then drag-and-drop onto the Origin workspace. An icon will appear in the Apps gallery window.
  • Operation
    Click the app icon to start this app by opening a dialog. Then load an image as source image (If the active window is image window, this active image is used as the source image for analysis.), and then insert operations by using the menu. You can also save or load the operations to or from a file. And after getting the target objects on image, you can output the measurement results of these objects.

Dialog Settings:

  • Operations Panel: This panel is used to handle the operations performed on the image to find objects.
    • Insert: Insert an operation after the selected operation in the list. When clicking this button, a menu shows up for inserting operation. Available operations include Source, Gray, Count Objects, Output Quantities, Threshold, Gaussian Blur, Gaussian Mixture Model, Canny Edge, Filter Edges By Length, Morphology, Fill Hole By Morphology, Filter Objects By Area, Filter Objects By Circularity, Filter Objects By Solidity, and Separate Objects By Watershed.
    • Remove: Remove selected operation from the operation list. Source, Gray, Count Objects and Output Quantities are fixed and cannot be removed.
    • Load Settings from File: Load operations from a file.
    • Save Settings to File: Save the current operation list to a file, so for use next time.
    • Save Settings to Image: Save operations to image window, so next time open this dialog with that image window active, the saved operations will be loaded automatically.

Reviews and Comments:
01/05/2022OriginLabHi mingear,
This App is updated to a new version. It supports for tif (tiff) format.
You can download a new one and try it.
Thanks

01/02/2022mingearA handy tool. Should be advertised/featured more. The input source should accept .tif files though.
