This repository contains measures for evaluating salient object detection models in python.

• E-measure
• S-measure
• Weighted F-measure
• Adaptive F-measure or F-measure
• MAE
• PR curve
• F-measure curve (different thresholds)

• opencv-python
• numpy
• scipy
• tqdm

Simply import calculate_measures, set Saliency Maps and Ground Truth paths, and choose measures you would like to be calculated (measures: 'MAE', 'E-measure', 'S-measure', 'Max-F', 'Adp-F', 'Wgt-F'). All results can be saved as numpy arrays by specifying save parameter.

>>> from saliency_toolbox import calculate_measures
>>> sm_dir = 'SM/'
>>> gt_dir = 'GT/'
>>> res    = calculate_measures(gt_dir, sm_dir, ['E-measure', 'S-measure', 'Wgt-F'], save=False)
>>> print(res)

{'E-measure': 0.990753, 'S-measure': 0.958684, 'Wgt-F': 0.974209}

To plot F-measure and Precision-Recall curves, firstly, Max-F should be calculated and stored (by specifying save). This results in storing Precision.npy, Recall.npy and Fmeasure_all_thresholds.npy, and then we can use them to plot curves. For example:

>>> res       = calculate_measures(gt_dir, sm_dir, ['Max-F'], save='./')
>>> prec      = np.load('save/Precision.npy')
>>> recall    = np.load('save/Recall.npy')
>>> f_measure = np.load('save/Fmeasure_all_thresholds.npy')
>>> plt.plot(recall, prec)
>>> plt.figure()
>>> plt.plot(np.linspace(0, 1, len(f_measure)), f_measure)
