Abstract

The invention discloses a cervical cell pathological slice automatic judging method with high and low resolution combination, which is characterized in that the method comprises the following steps: extracting a single cell mass region on a low-resolution cervical pathological slice image; extracting a single cell mass region from the low-resolution cervical pathological slice image; identifying suspicious abnormal cell clusters from low-resolution cell clusters; mapping suspected abnormal cell mass regions into high resolution slice images; semantically segmenting pathological cells from thehigh-resolution region of suspicious cell clusters and interpreting the type; according to the type, quantity and confidence of the segmented lesion cells, establishing the feature set of the slice, and then classifying the lesion type of the whole slice. The invention takes cell cluster as processing and recognition unit, utilizes classification neural network model to quickly identify suspiciousabnormal cell cluster on low-resolution digital slice, then divides out pathological cell on high-resolution suspicious area and judges its type, at the same time, improves recognition accuracy and recognition efficiency.

Description

technical field [0001] The invention belongs to the field of medical cytopathological image processing, and more specifically relates to an automatic interpretation method for cervical cytopathological slices combined with high and low resolution. Background technique [0002] Cervical cancer is a malignant tumor with high incidence in women. Cervical liquid-based cytopathology is currently the most important means of preventing and screening cervical cancer. Accurate interpretation of diseased cells in cytopathological slice images is an important basis for doctors to determine the patient's condition and formulate a treatment plan. At present, the manual interpretation of cytopathological images is not only time-consuming, but also the interpretation results are very dependent on the experience of doctors. Therefore, automatically interpreting diseased cells in pathological slides can not only improve the efficiency of diagnosis but also provide doctors with a more unifi...
