 +  * **Block filtering:​** Increasing this parameter increases the amount of filtering Pixy2 applies to the detection of each block. ​ Increasing this parameter can reduce the false positive detections, but will also increase the amount of time it takes between the object appearing in the frame and it being reported by Pixy2.
 +  * **Max tracking velocity:** This parameter sets the maximum distance a detected object can travel between frames. ​ In other words, objects that exceed this _velocity_ will be considered invalid. ​ Decreasing this parameter can reduce the false positive detections, especially if you don't expect your detected objects to move very much from frame to frame. ​ The value is specified in pixels per frame period (16.7 milliseconds).
 +  * **Max blocks:** This parameter sets maximum total number of blocks (objects) Pixy2 will report per frame. For example, if you set this parameter to 2, Pixy2 will report a maximum of 2 objects (the 2 largest objects) regardless of which signature the blocks belong to, and all other detected objects will not be reported.
 +  * **Max blocks per signature:​** This parameter sets the maximum number of blocks (objects) Pixy2 will report per signature, per frame. For example, if you set this parameter to 2, Pixy2 will report a maximum of 2 objects for each signature (the largest objects in the frame) and all other detected objects with that signature will not be reported.
 +  * **Max merge dist:** Pixy2 will combine objects that have the same signature and are sufficiently close together in the frame. ​ This parameter adjusts this distance. ​ Increasing this parameter will result in Pixy2 merging more detected blocks together into a single block.
 +  * * **Min block area:** sets the minimum area of reported blocks. If a detected block has a smaller area, it will not be reported. For this purpose, area of a block is calculated as width * height.
 +  * **LED brightness:​** sets the brightness of Pixy2'​s RGB LED. Pixy2'​s LED is quite bright if you want it to be (too bright to look at!)
 +  * **Signature teach threshold:​** This parameter applies when you are teaching Pixy2 a signature using the button-push method. It allows you to adjust how inclusive Pixy2 is when determining which pixels are part of the object you are trying to teach it. You can find more information [[wiki:​v2:​Some_Tips_on_Generating_Color_Signatures_2|here]].
 +  * **Color code mode:** This parameter sets the behavior of color codes, including enabling/​disabling. ​ Options include:
 +    * **Enabled:​** Color codes are enabled, normal mode.\\
 +    * **Disabled:​** Color codes are disabled.\\
 +    * **Color codes only:** Only color codes are reported. Objects that match non-color-code signatures will not be reported.\\
 +    * **Mixed:** This is the same as normal color code mode, but Pixy2 will also report color-code signatures that aren't part of color codes. (Normally, Pixy2 only reports color-code signatures that are part of color codes -- 2 or more color-code signatures that are close together.)
