   .. tab:: Confidence Threshold
 
-    - **Confidence threshold**: Stereo depth algorithm searches for the matching feature from right camera point to the left image (along the 96 disparity levels). During this process it computes the cost for each disparity level and chooses the minimal cost between two disparities and uses it to compute the confidence at each pixel. Stereo node will output disparity/depth pixels only where depth confidence is below the **confidence threshold** (lower the confidence value means better depth accuracy). Note: This threshold only applies to Normal stereo mode as of now.
