As our results demonstrated we were able to get up to 0.9 frames per second, which is not fast enough to constitute real-time detection.That said, given the limited processing power of the Pi, 0.9 frames per second is still reasonable for some applications. 1). Since face detection is such a common case, OpenCV comes with a number of built-in cascades for detecting everything from faces to eyes to hands to legs. Below you can see a couple of short videos that illustrates how well our model works for fruit detection. Clone or size by using morphological feature and ripeness measured by using color. Unexpectedly doing so and with less data lead to a more robust model of fruit detection with still nevertheless some unresolved edge cases. Here we shall concentrate mainly on the linear (Gaussian blur) and non-linear (e.g., edge-preserving) diffusion techniques. Theoretically this proposal could both simplify and speed up the process to identify fruits and limit errors by removing the human factor. The average precision (AP) is a way to get a fair idea of the model performance. We performed ideation of the brief and generated concepts based on which we built a prototype and tested it. Once the model is deployed one might think about how to improve it and how to handle edge cases raised by the client.
