Hi Asuka,
Sorry, I did not realize that. I was exhausted from working on a project. To address your issue of getting the correct missing rate in your training and testing steps, several modifications need to be made to your existing code. Firstly, ensure that the paths specified for loading the ground truth data and test images are accurate and pointing to the correct locations. Next, it seems that you are overwriting the ground truth locations for `testPath` without defining `gTruthTrain` first. Make sure that `gTruthTrain` is properly defined before calling `overwriteGTruthLocations(gTruthTrain)`. Additionally, when loading the test ground truth data using `WoodKnotsGroundTruthTest2.mat`, make sure that the data is correctly formatted and matches the structure expected by the subsequent functions. Moreover, you are redefining `imdsTest` as an imageDatastore after training the ACF object detector. It is recommended to load and preprocess the test images before training the detector. Finally, when evaluating the detection miss rate using `evaluateDetectionMissRate`, ensure that the bounding boxes (`bboxes`) and label data from `gTruthTest` are correctly aligned and formatted for accurate assessment. Here is a revised version of your code with the necessary modifications:
load("C:\Users\xxoox\OneDrive\デスクトップ\MATLAB works\Computer Vision for Engineering and Science\C2-MachineLearningForComputerVision\Module 4\WoodKnotsGroundTruth.mat");
gTruthTrain = gTruth; % Define gTruthTrain
testPath = overwriteGTruthLocations(gTruthTrain);
imageLabeler(gTruthTrain) imageLabeler(testPath)
load("C:\Users\xxoox\OneDrive\デスクトップ\MATLAB works\Computer Vision for Engineering and Science\C2-MachineLearningForComputerVision\Module 4\WoodKnotsGroundTruthTest2.mat");
imdsTest = imageDatastore(testPath);
objectTrainingData = objectDetectorTrainingData(gTruthTrain) acfDetector = trainACFObjectDetector(objectTrainingData)
bboxes = detect(acfDetector,imdsTest)
evaluateDetectionMissRate(bboxes,gTruthTest.LabelData)
Feel free to test this updated code and let me know if you encounter any further issues or require additional assistance.
