Soft Filter Does Very Little

[jbrownkramer]

Describe the bug I have added a call to k4a_device_enable_soft_filter in the hopes that it would filter depth less aggressively than the previous version of the SDK. That does not seem to be the case. I fail to see a significant difference between the depth image with Soft Filter True and Soft Filter False.

Here is a surface normal image with it set false:

Here it is set true:

To Reproduce Add the end of the code that opens the cameras, call ::k4a_device_enable_soft_filter(device, false); or ::k4a_device_enable_soft_filter(device, true);

Expected behavior Some notable difference in the depth images. Hopefully less aggressive filtering than the default.

Desktop (please complete the following information):

• OS with Version: Windows 11
• SDK Version: 1.9.3

Currently using default parameters, we are considering adding corresponding coordination parameters to the interface in the future

Current expected output:

Depth resolution: 1024*1024

Depth resolution: 640*576

Depth resolution: 512*512

Depth resolution: 320*288

Interesting! Is it on or off by default? Do you have info on how fast the soft filter is?
