Request steps and .YML example to create mask: 'image : mask02.bmp'

I have two disconnected areas that I do not want detection to include, so I am of the understanding that I need to go with an image mask.

Can someone share the steps to create the right format image mask file? I created a black and white .BMP file from a:
http://192.168.1.100:5000/cam-01/latest.jpg
image.

But I don't thing I have the image correct. Correct dimensions? Correct depth? Correct format? Where and how in the .YML file to put the configuration?

If someone can share a set of steps and configuration that is working for them, that would be appreciated. Thx!

Dimensions should be the same as your camera, depth could be 1bit, format is BMP. Then you just put in the mask file in your config directory and the filename in the config file.

frigate/README.md

Lines 270 to 273 in a1cc9ad

	# Optional: motion mask
	# NOTE: see docs for more detailed info on creating masks
	mask: poly,0,900,1080,900,1080,1920,0,1920

However I would reccomend using a Poly mask and make a very thin connecting line between the two areas, you could make it 0px wide if you go straight across and tweak it by hand. I think v0.8 will have support for a list of poly masks which would be good for your circumstance.

	## Masks
	The following types of masks are supported:
	- `poly`: (Recommended) List of x,y points like zone configuration
	- `base64`: Base64 encoded image file
	- `image`: Image file in the `/config` directory
	`base64` and `image` masks must be the same aspect ratio and resolution as your camera.
	The mask in the second image would limit motion detection on this camera to only the front yard and not the street.

	To create a poly mask:
	1. Download a camera snapshot image with the same resolution as the camera feed (`/<camera_name>/latest.jpg`).
	1. Upload the image to https://www.image-map.net/
	1. Select "shape" poly - start in the lowest left corner and place the first marker (point) and continue upwards and then to the right until the polygon shape covers the area that you want to mask out (ignore).
	1. When you are finished with the polygon click "Show me the code!" and copy all coordinates (point), ie. `"0,461,3,0,1919,0,1919,843,1699,492,1344,458,1346,336,973,317,869,375,866,432"`
	1. Adjust any -1 values to 0 and then add it all to the configuration (see the example configuration for correct indentation and placement)
	Example of a finished row corresponding to the below example image:
	```yaml
	mask: 'poly,0,461,3,0,1919,0,1919,843,1699,492,1344,458,1346,336,973,317,869,375,866,432'
	```

	You can test your mask by temporarily configuring it as a [zone](#zones) and enabling `draw_zones` in your config. Zones are visible on the [MJPEG feed](#camera_name).
