vitis::ai::MedicalSegcell

Base class for segmenting nuclei from images of cells.

Input is an image (cv:Mat).

Output is a struct of detection results, named MedicalSegcellResult.

Sample code :

Mat img = cv::imread("sample_medicalsegcell.jpg");
auto medicalsegcell =
vitis::ai::MedicalSegcell::create("medical_seg_cell_tf2",true);
auto results = medicalsegcell->run(img);
// results is structure holding cv::Mat.
// please check test samples for detail usage.

Returns

MedicalSegcellResult.

run

Function to get running results of the MedicalSegcell neuron network in batch mode.

Prototype

std::vector< vitis::ai::MedicalSegcellResult > run(const std::vector< cv::Mat > &imgs)=0;

Parameters

The following table lists the run function arguments.

Table 4. run Arguments
Type	Name	Description
const std::vector< cv::Mat > &	imgs	Input data of input images (vector<cv::Mat>).The size of input images equals batch size obtained by get_input_batch.

Returns

The vector of MedicalSegcellResult.

getInputWidth

Function to get InputWidth of the MedicalSegcell network (input image columns).

Prototype

Prototype

int getInputHeight() const =0;

Returns

InputHeight of the MedicalSegcell network.

get_input_batch

Function to get the number of images processed by the DPU at one time.

Note: Different DPU core the batch size may be different. This depends on the IP used.
