Image ROI Select Multi
The
Image ROI Select Multi node in AugeLab Studio allows you to select multiple rectangular regions of interest (ROI) by dragging the mouse over an image. It provides a user interface to interactively define multiple ROI rectangles by specifying the top-left and bottom-right corners of each rectangle.The
Image ROI Select Multi node takes an image as input and provides the following outputs:- 1.Image List: A list of region of interest (ROI) images extracted from the input image. Each element in the list represents a cropped image representing one of the specified ROI rectangles.
- 2.Area Coordinates: The coordinates of the top-left and bottom-right corners of each ROI rectangle. The coordinates are provided as a list of tuples
[((x1, y1), (x2, y2)), ...], where each tuple represents the top-left and bottom-right corners of a rectangle.
- Node Title: Image ROI Select Multi
- Node ID: OP_NODE_ROI_MOUSE_MULTI
The
Image ROI Select Multi node has the following input socket:- 1.Image: The input image on which the ROI rectangles will be defined.

The
Image ROI Select Multi node provides a user interface within AugeLab Studio to interactively select multiple rectangular ROIs using the mouse. Here are the UI features and interactions:- Drag: Click and drag the mouse over the image to define each ROI rectangle. The top-left corner is defined by the initial click, and the bottom-right corner is defined by releasing the mouse button.
- Rectangles: While dragging the mouse, rectangles are displayed in real-time to indicate the selected ROI regions.
- Update: The displayed rectangles dynamically update as you drag the mouse, allowing you to preview the selected regions before finalizing the selections.
- Clear and Undo: Press the C key to clear all the rectangles and start over. Press the U key to undo the last added rectangle.
- 1.Drag and drop the
Image ROI Select Multinode from the node library onto the canvas in AugeLab Studio. - 2.Connect the input image to the Image input socket of the
Image ROI Select Multinode. - 3.Run the pipeline.
- 4.The
Image ROI Select Multinode displays the input image in the node view. - 5.Click and drag the mouse over the image to define multiple ROI rectangles. Each initial click defines the top-left corner, and releasing the mouse button defines the bottom-right corner of a rectangle.
- 6.As you drag the mouse, rectangles dynamically update in real-time to indicate the selected ROI regions.
- 7.Release the mouse button to finalize the selection of each rectangle.
- 8.The
Image ROI Select Multinode outputs a list of cropped ROI images and a list of the coordinates of the top-left and bottom-right corners of each ROI rectangle. - 9.Retrieve the output image list and area coordinates list for further processing or analysis.
- The
Image ROI Select Multinode provides an interactive way to select multiple rectangular regions of interest (ROI) by dragging the mouse over an image. - Use the left mouse button to click and drag over the image to define the top-left and bottom-right corners of each ROI rectangle.
- The displayed rectangles dynamically update in real-time as you drag the mouse, allowing you to preview the selected regions.
- You can add and modify multiple ROI rectangles in the same image.
- Press the C key to clear all the rectangles and start over.
- Press the U key to undo the last added rectangle.
- The selected ROI images and area coordinates can be used for further processing, analysis, or visualization in subsequent nodes.
That concludes the documentation for the
Image ROI Select Multi node in AugeLab Studio. Use this node to select multiple rectangular regions of interest (ROI) by dragging the mouse over an image.
