Use the model

You can use this model in the Detect Objects Using Deep Learning tool available in the Image Analyst toolbox in ArcGIS Pro. Follow the steps below to use the model for detecting cooling towers in images. This model can also be fine-tuned using Train Deep Learning Model tool. See Fine-tune the model page for details on how to fine-tune this model.

Detect cooling towers

Use the following steps to detect cooling towers from the imagery:

1. Download the Cooling Tower Detection - USA model and add the imagery layer in ArcGIS Pro.
2. Zoom to an area of interest.

   

3. Browse to Tools under the Analysis tab.

   

4. Click the Toolboxes tab in the Geoprocessing pane, select Image Analyst Tools, and browse to the Detect Objects Using Deep Learning tool under Deep Learning.

   

5. Set the variables under the Parameters tab as follows:
   1. Input Raster—Select the imagery.
   2. Output Detected Objects—Set the output feature class that will contain the detected objects.
   3. Model Definition—Select the pretrained or fine-tuned model .dlpk file.
   4. Arguments—Change the values of the arguments if required.
      • padding—The number of pixels at the border of image tiles from which predictions are blended for adjacent tiles. Increase its value to smooth the output while reducing edge artifacts. The maximum value of the padding can be half of the tile size value.
      • batch_size—The number of image tiles processed in each step of the model inference. This depends on the memory of your graphics card.
      • threshold—The detections that have a confidence score higher than this threshold are included in the result. The allowed values range from 0 to 1.0.
      • return_bboxes—If True, the tool will return a bounding box around the detected feature.
      • test_time_augmentation—Performs test time augmentation while predicting. This is a technique used to improve the robustness and accuracy of model predictions. It involves applying data augmentation techniques during inferencing, which means generating multiple slightly modified versions of the test data and aggregating the predictions. If true, predictions of flipped and rotated orientations of the input image will be merged into the final output and their confidence values are averaged. This may cause the confidence to fall below the threshold for objects that are only detected in a few orientations of the image.
      • merge_policy—The policy for merging augmented predictions. Available options are mean, max, and min. This is only applicable when test time augmentation is used.
      • tile_size—The width and height of image tiles into which the imagery is split for prediction.
   5. Non Maximum Suppression—Optionally, check the check box to remove the overlapping features with lower confidence.

      If checked, do the following:

      • Set Confidence Score Field.
      • Optionally, set Class Value Field.
      • Optionally, set Max Overlap Ratio.

   

6. Set the variables under the Environments tab as follows:
   1. Processing Extent—Select Current Display Extent or any other option from the drop-down menu.
   2. Cell Size (required)—Set the value as resolution of the imagery. You can keep the default value to pick the imagery extent by default.
   3. Processor Type—Select CPU or GPU.

      It is recommended that you select GPU, if available, and set GPU ID to the GPU to be used.

   

7. Click Run.

   The output layer is added to the map.
