Suppose we are presented with two categories of skin lesions: benign and malignant. Our objective is to sift out benign images that bear resemblance to malignant ones, and similarly, malignant images that bear resemblance to benign ones.
from cossif import cossifcsf = cossif.CosSIF()# Filter benign images
csf.calculate_and_filter(
target_path=cls_benign, # Path to the folder that contains benign images.
secondary_path=cls_malignant, # Path to the folder that contains malignant images.
filtered_path=cls_benign_filtered, # Path to the folder that will contain filtered benign images.
removed_path=cls_benign_removed, # Path to the folder that will contain removed benign images.
record_save_path=save_path, # Save path of the similarity calculation record.
record_keep=False, # Chose whether to keep the similarity calculation record or not.
file_name='t_benign_x_s_malignant', # Name of the similarity calculation record file.
filter_type='dissimilar', # Type of filtering. Can be either "similar" or "dissimilar".
filter_range=0.85, # The filtering ratio. A value of 0.85 means that 15% of the images will be removed.
)
# Filter malignant images
csf.calculate_and_filter(
target_path = cls_malignant,
secondary_path = cls_benign,
filtered_path=cls_malignant_filtered,
removed_path=cls_malignant_removed,
record_save_path = save_path,
record_keep=False,
file_name = 't_malignant_x_s_benign',
filter_type = 'similar',
filter_range = 0.85,
)
