Structs
Public-facing structs for Edge Impulse C++ SDK.
ei_impulse_result_classification_t
Holds the output of inference, anomaly results, and timing information.
ei_impulse_result_t
holds the output of run_classifier()
. If object detection is enabled, then the output results is a pointer to an array of bounding boxes of size bounding_boxes_count
, as given by ei_impulse_result_bounding_box_t. Otherwise, results are stored as an array of classification scores, as given by ei_impulse_result_classification_t.
If anomaly detection is enabled (e.g. EI_CLASSIFIER_HAS_ANOMALY == 1
), then the anomaly score will be stored as a floating point value in anomaly
.
Timing information is stored in an ei_impulse_result_timing_t struct.
Source: classifier/ei_classifier_types.h
Example: standalone inferencing main.cpp
Member | Description |
---|---|
| Label of the detected object |
| Value of the detected object |
ei_impulse_visual_ad_result_t
Holds the output of visual anomaly detection (FOMO-AD)
If visual anomaly detection is enabled (e.g. EI_CLASSIFIER_HAS_VISUAL_ANOMALY == 1
), then the output results will be a pointer to an array of grid cells of size visual_ad_count
, as given by ei_impulse_result_bounding_box_t.
The visual anomaly detection result is stored in visual_ad_result
, which contains the mean and max values of the grid cells.
Source: classifier/ei_classifier_types.h
Example: standalone inferencing main.cpp
Member | Description |
---|---|
| Mean value of the grid cells |
| Max value of the grid cells |
ei_impulse_result_bounding_box_t
Holds information for a single bounding box.
If object detection is enabled (i.e. EI_CLASSIFIER_OBJECT_DETECTION == 1
), then inference results will be one or more bounding boxes. The bounding boxes with the highest confidence scores (assuming those scores are equal to or greater than EI_CLASSIFIER_OBJECT_DETECTION_THRESHOLD
), given by the value
member, are returned from inference. The total number of bounding boxes returned will be at least EI_CLASSIFIER_OBJECT_DETECTION_COUNT
. The exact number of bounding boxes is stored in bounding_boxes_count
field of [ei_impulse_result_t]/C++ Inference SDK Library/structs/ei_impulse_result_t.md).
A bounding box is a rectangle that ideally surrounds the identified object. The (x
, y
) coordinates in the struct identify the top-left corner of the box. label
