pyrealsense2.temporal_filter

class pyrealsense2.temporal_filter

Temporal filter smooths the image by calculating multiple frames with alpha and delta settings. Alpha defines the weight of current frame, and delta defines thethreshold for edge classification and preserving.

__init__(*args, **kwargs)

Overloaded function.

1. __init__(self: pyrealsense2.temporal_filter) -> None

2. __init__(self: pyrealsense2.temporal_filter, smooth_alpha: float, smooth_delta: float, persistence_control: int) -> None

Possible values for persistence_control: 1 - Valid in 8/8 - Persistency activated if the pixel was valid in 8 out of the last 8 frames 2 - Valid in 2 / last 3 - Activated if the pixel was valid in two out of the last 3 frames 3 - Valid in 2 / last 4 - Activated if the pixel was valid in two out of the last 4 frames 4 - Valid in 2 / 8 - Activated if the pixel was valid in two out of the last 8 frames 5 - Valid in 1 / last 2 - Activated if the pixel was valid in one of the last two frames 6 - Valid in 1 / last 5 - Activated if the pixel was valid in one out of the last 5 frames 7 - Valid in 1 / last 8 - Activated if the pixel was valid in one out of the last 8 frames 8 - Persist Indefinitely - Persistency will be imposed regardless of the stored history(most aggressive filtering)
