Abstract

The invention discloses a videodisc detection method based on a convolutional neural network and a videodisc detection system thereof. Supervised learning is performed by using a deep convolutional neural network so that the discriminate characteristics can be better learnt, and the expression capability of the model can be better enhanced by using the RGV image and the rectangular area of interest. The robustness and the accuracy of the training model can be effectively enhanced by multilevel training, and the efficiency of the model can also be enhanced by the probability guided detection method so that the problems of less sample, image complexity and poor quality can be overcome, and the videodisc detection task can be efficiently and accurately completed.

Description

technical field [0001] The invention relates to the field of ophthalmic medical image processing, in particular to an optic disc detection method based on a convolutional neural network. Background technique [0002] The optic disc is the part of the retina where visual fibers and blood vessels come together and exit the eyeball, and is the beginning of the optic nerve. The detection of the optic disc is of great significance in the automatic processing and analysis of fundus images. In actual application scenarios, due to the existence of various diseases and different image acquisition settings, the detection of optic discs still has great challenges. In recent years, the detection work of optic discs has mainly focused on unsupervised methods, which still have certain deficiencies in accuracy and efficiency. With the deepening of the application of statistical theory and machine learning theory in the field of medical image processing, more and more methods based on sup...
