Interface Functions

  1. mmind_packInfer_create

    int mmind_packInfer_create(Engine* engine, const char* packPath);

    Parse the dlkpack file and create the corresponding inference engine.

    Input parameters:

    • engine: Inference engine information (pointer).

    • packPath: dlkpack file path.

    Returned value:

  2. mmind_packInfer_destroy

    int mmind_packInfer_destroy(Engine engine);

    Unregister the inference engine.

    Input parameter:

    • engine: Inference engine information.

    Returned value:

  3. mmind_packInfer_infer

    int mmind_packInfer_infer(Engine engine, Image* img, Image* segMask, Image* insegMask, int& maskNumber, int* h, int* w, int& labelNumber, int* labels, int& bboxNumber, float* bboxes, int& confidenceNumber,  float* confidences);

    Let the inference engine perform inference.

    Input parameters:

    • engine: Inference engine information.

    • img: Input image.

    • segMask: Mask result for defect segmentation.

    • insegMask: Mask result for instance segmentation.

    • maskNumber: Number of instance segmentation masks.

    • h: Mask image height for instance segmentation.

    • w: Mask image width for instance segmentation.

    • labelNumber: Number of labels.

    • labels: Inference result labels.

    • bboxNumber: Number of bounding boxes.

    • bboxes: Bounding box coordinates. Each 4 values (upper left X, upper left Y, lower right X, lower right Y) are for one box.

    • confidenceNumber: Number of result confidences.

    • confidences: Result confidences.

    Returned value:
