filefunction / class

Why would anyone build with this?

REASON 1

Test a newly trained object detection model on an Android phone without writing a custom test app.

REASON 2

Compare your own model's output against model-zoo baselines like YOLO or Openpose on-device.

REASON 3

Prototype a robotics or vision project by capturing live camera feed and running inference in real time.

REASON 4

Compress and optimize a computer vision model so it runs within a phone's battery and memory limits.

Yoink these prompts

Prompt 1
Using DeepVision's Script API, help me write a configuration file to load a YOLO model and run it on live camera input without writing any Java code.
Prompt 2
Show me how to use DeepVision's Java API to load an image from the gallery, run pose estimation, and display the keypoints on screen.
Prompt 3
I want to compress my trained model using DeepVision's optimization tools so it runs faster on a low-end Android device, walk me through the steps.
Prompt 4
Help me use DeepVision's Native C/C++ API to integrate a custom face recognition model for maximum inference performance.
Prompt 5
Using DeepVision's model zoo, show me how to compare my custom object detection model's accuracy against the included Openpose baseline.
