otx.api.utils.vis_utils

This module implements activation map.

Functions

dump_frames(saved_frames, output, ...)	Saves images/videos with predictions from saved_frames to output folder with proper names.
get_actmap(saliency_map, output_res)	Get activation map (heatmap) from saliency map.
get_input_names_list(input_path, capture)	Lists the filenames of all inputs for demo.

otx.api.utils.vis_utils.dump_frames(saved_frames: list, output: str, input_path: str | int, capture)

Saves images/videos with predictions from saved_frames to output folder with proper names.

otx.api.utils.vis_utils.get_actmap(saliency_map: ndarray, output_res: tuple | list) → ndarray

Get activation map (heatmap) from saliency map.

It will return activation map from saliency map

Parameters:

• saliency_map (np.ndarray) – Saliency map with pixel values from 0-255

• output_res (Union[tuple, list]) – Output resolution

Returns:

[H, W, 3] colormap, more red means more salient

Return type:

saliency_map (np.ndarray)

otx.api.utils.vis_utils.get_input_names_list(input_path: str | int, capture)

Lists the filenames of all inputs for demo.
