From __init__.py:

Class ArrayModel A model for an array.
Class BaseCamera The base class for all cameras. All cameras must directly inherit from this class.
Class CameraMemoryBuffer A class that holds images in memory. The images are by default PIL images.
Class JPEGBlob A class representing a JPEG image as a LabThings FastAPI Blob.
Class PNGBlob A class representing a PNG image as a LabThings FastAPI Blob.
Exception CaptureError An error trying to capture from a CameraThing.
Exception NoImageInMemoryError An error called if no image is in memory when accessed.
Function downsample Downsample an image by taking the mean of each nxn region.

def downsample(factor: int, image: np.ndarray) -> np.ndarray: (source)

Downsample an image by taking the mean of each nxn region.

This should be very efficient:

  • calculate each pixel as the mean of each factor * factor square without
    interpolation.
  • If the image is not an integer multiple of the resampling factor, discard
    the left-over pixels to avoid odd edge effects and keep performance quick.
