Solution

Face detection

Android Studio, NDK, SDK versions (if issue is related to building in Android environment)

No response

Xcode & Tulsi version (if issue is related to building for iOS)

No response

Describe the actual behavior

Sample code provided in github works well for the face_detection_short_range.tflite model but not working for face_detection_full_range_sparse.tflite model.

Describe the expected behaviour

Expected behavior is , it should work with face_detection_full_range_sparse.tflite model also, which provides range over 5m for the face detection.

Standalone code/steps you may have used to try to get what you need

Steps to Reproduce 1. Change the model name to 'val modelName = "face_detection_full_range_sparse.tflite" ' 2. Download model from the https://github.com/google-ai-edge/mediapipe/blob/master/docs/solutions/models.md and copy it to assets folder. 3. Comment //apply from:'download_models.gradle' from an app buid.gradle file. 4. Clean the build and run the application 5. Select Camera tab from the application. 6. In logs it give below error and face not get detected.

Hi @poonamilekar,

We have a newer version available (0.10.20). Please try it and let us know if the issue persists. Also, confirm whether you are testing on an emulator or a physical device.

Thank you!!

Thank you @kuaashish for the reply.
However newer version is also giving same error and testing is on physical device only.
