This tab contains more advanced parameters for adjusting various color connected components things. To bring up this tab, you must be running the color_connected_components program by selecting in the Program menu, and then bring up the Configure Dialog (click on the gear icon or select File➜Configure). Now select the Expert tab under Pixy Parameters.

* **Block filtering:** asdf
* **Max tracking velocity:** asdf
* **Max blocks:** This parameter sets maximum total number of blocks (objects) Pixy will report per frame. For example, if you set this parameter to 2, Pixy 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) Pixy will report per signature, per frame. For example, if you set this parameter to 2, Pixy will report a maximum of 2 objects for each signature, and all other detected objects with that signature will not be reported.
* **Max merge dist:**
* **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 Pixy's RGB LED. Pixy'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 Pixy a signature using the button-push method. It allows you to adjust how inclusive Pixy is when determining which pixels are part of the object you are trying to teach. 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. Hovering the mouse over the parameter will provide information on the available settings.\\

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 Pixy will also report color-code signatures that aren't part of color codes. (Normally, Pixy only reports color-code signatures that are part of color codes – 2 or more color-code signatures that are close together.)

• Default program: This parameter sets the program that gets executed upon power-up. The available programs are listed in the pulldown menu.
• Program select on power-up:
• Debug: sets the debug level within Pixy. Setting the value to 0 means that no debugging information is displayed.
