accuracy of tflite model

[oHuflying]

The results are accurate on large models, but on the TFLITE model, the results are often a little smaller than the edges of the object. Assuming a sphere with a radius of 100 pixels in the original image, the sphere on the depth map may only have 98 pixels after the depth map is scaled up to the original size, I suspect that this may be the result of some kind of error, since edge detection is usually simple and accurate
