Bloom Filter

Filter

RIF_IMAGE_FILTER_BLOOM

Description

One of the filters that help reproduce real-world camera effects. Produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of an extremely bright light overwhelming the camera or eye capturing the scene.

Parameters

Parameter	Type	Input/Output	Description
radius	float	input	Filter radius (relative to image dimensions). Actual radius in pixels is calculated in kernel as `radius_in_pixels` = `image_width` * `radius`. Value range is [0.01, 1], default value is 0.1.
threshold	float	input	Pixels with values below that wouldn’t be taken into account. Default value is 0.
weight	float	input	Area sum is multiplied by the weight value. Default value is 0.1.
decay	float	input	Light intensity decay, default value is 1 (no decay).
