Anthropometric System

Body measurement extraction using Open Pose

WPF Application (WpfApp1)

The solution includes a WPF project named WpfApp1. Its specific purpose and interaction with the main AnthropometricMeasure web application are not clear from the existing codebase. It does not appear to be directly involved in the image processing or measurement calculation workflow.

Recommendation: Review the WpfApp1 project. If it is no longer needed or is an unfinished component, consider removing it to simplify the solution. If it serves a purpose (e.g., as a utility, for testing, or a separate tool), its functionality and any relationship with the web application should be documented.

Testing Recommendations

To improve the robustness and maintainability of this project, adding automated tests is highly recommended. Consider the following areas for unit and integration testing:

Unit Tests

• DistanceAlgo.cs:
  • Test distanceBetweenPoints() with various inputs (zero distance, positive/negative coordinates, points on axes).
• MatrixCal.cs:
  • Thoroughly test all matrix operations: MatrixCreate, MatrixProduct, MatrixInverse, MatrixIdentity. Include tests for valid inputs, edge cases, and invalid inputs (e.g., incompatible dimensions, singular matrices for inversion).
• JsonRead.cs (LoadJson method):
  • Test with valid sample JSON (confirming correct MeasurementModel population).
  • Test with malformed/invalid JSON.
  • Test with JSON files missing expected keypoints or data.
  • Test with non-existent JSON file paths.
• RatioAlgo.cs (matrixwcal method):
  • Verify that matrixwcal() produces the expected matrixw output given its hardcoded input matrices. This acts as a regression test for the calibration logic.

Integration Tests

• ImageUploadController.cs (PostFormData method):
  • Test successful image upload and (simulated) OpenPose processing, verifying the correct HTTP response and that the dummy JSON output is created as expected.
  • Test with invalid file types (e.g., .txt, .exe).
  • Test with files exceeding the defined size limits.
  • Test behavior when no file is uploaded.
• MeasurementController.cs (GetMeasurement method):
  • Test with a valid jsonPath query parameter, ensuring correct MeasurementModel retrieval.
  • Test with a missing or empty jsonPath.
  • Test with jsonPath values that are invalid (e.g., outside the allowed directory, non-existent file).

Consider using a testing framework like MSTest, NUnit, or xUnit for implementing these tests.

Configuration

The application uses settings in the Web.config file's <appSettings> section for key configurations:

Image Processing and Upload (ImageUploadController)

• OpenPoseExePath:

  • Purpose: Specifies the full path to the OpenPose executable (e.g., OpenPoseDemo.exe or similar). This is used to process the uploaded images.
  • Example: <add key="OpenPoseExePath" value="C:\Program Files\OpenPose\bin\OpenPoseDemo.exe" />
  • Note: The application will return a server error if this path is not configured or is invalid. The actual OpenPose execution is currently simulated in the code.

• AllowedUploadExtensions:

  • Purpose: A comma-separated list of allowed file extensions for image uploads.
  • Example: <add key="AllowedUploadExtensions" value=".jpg,.jpeg,.png,.bmp,.gif" />
  • Default (if not set or invalid): .jpg,.jpeg,.png

• MaxUploadFileSizeInBytes:

  • Purpose: The maximum allowed file size for uploads, specified in bytes.
  • Example: <add key="MaxUploadFileSizeInBytes" value="10485760" /> (for 10 MB)
  • Default (if not set or invalid): 10485760 (10 MB)

Measurement Calibration (RatioAlgo)

These settings are critical for the RatioAlgo to calculate final measurements. The application will throw a configuration error on startup if these are missing or malformed.

• RatioAlgo.Lambda:

  • Purpose: The regularization parameter (lambda) used in the matrix calculations.
  • Example: <add key="RatioAlgo.Lambda" value="0.50" />

• RatioAlgo.MatrixX:

  • Purpose: A comma-separated string of 7 double values representing the 'matrixx' calibration vector.
  • Example: <add key="RatioAlgo.MatrixX" value="72.597,61.504,56.222,115.277,45.382,89.17,72.683" />

• RatioAlgo.MatrixY:

  • Purpose: A comma-separated string of 7 double values representing the 'matrixy' calibration vector.
  • Example: <add key="RatioAlgo.MatrixY" value="44,33,27,63,23,51,45" />
