Sensor

class dnois.sensor.Sensor(pixel_num: int | tuple[int, int], pixel_size: float | tuple[float, float])

A basic sensor model.

Parameters:

• pixel_num (int or tuple[int, int]) – Numbers of pixels in vertical and horizontal directions.

• pixel_size (float or tuple[float, float]) – Height and width of a pixel in meters.

extra_repr() → str

Return the extra representation of the module.

To print customized extra information, you should re-implement this method in your own modules. Both single-line and multi-line strings are acceptable.

forward(radiance: Tensor) → Tensor

Returns the input radiance field reaching the sensor plane instantaneously.

Parameters:

radiance (Tensor) – Radiance field of shape \((\ldots, N_\text{wl}, H, W)\).

Returns:

radiance itself.

Return type:

Tensor
