I have noticed that the memory usage of my MacOS app increases about 84MB when I use VNDetectHumanHandPoseRequest, and this extra memory usage remains even after I release all associated objects.
I was able to create a small sample code, which reproduces this behavior.

Code Block @IBAction func toggleGesture(_ sender:NSMenuItem) { gestureEnabled = !gestureEnabled sender.state = gestureEnabled ? .on : .off if gestureEnabled { handPoseRequest = VNDetectHumanHandPoseRequest() } else { handPoseRequest = nil } } public func captureOutput(_ output: AVCaptureOutput, didOutput sampleBuffer: CMSampleBuffer, from connection: AVCaptureConnection) { guard let request = handPoseRequest else { return } let handler = VNImageRequestHandler(cmSampleBuffer: sampleBuffer, orientation: .up, options: [:]) do { try handler.perform([request]) let results = request.results if let count = results?.count, count > 0 { print("results.count", count) } } catch { print("Vision Error", error.localizedDescription) } }
