Embodiment Construction

[0034] The present invention will be further described below in conjunction with accompanying drawings and examples.

[0035] like figure 1 As shown, a method for identifying cast components based on urinary_8Net urinary sediment casts according to the present invention mainly includes the following steps:

[0036] Step 1: Collect the segmented urinary sediment casts and randomly divide them into a training set and a test set at a ratio of 4:1;

[0037] Microscope images of urine formed components were collected, and the urine formed components in the images were marked. A total of 9272 pictures of urinary sediment casts were obtained, including 4 different categories: pathological casts and transparent casts , mucus filaments, and cast-like components.

[0038] The data volume of these two types of urine formed components of casts is relatively small, among which there are 1010 pictures of transparent casts and 1953 pictures of pathological casts, so it is necessary to appl...

Abstract

The invention relates to a method for identifying transparent tube type, pathological tube type and mucus silk in urinary sediment, which comprises the following steps: 1, collecting segmented urine visible component microscopic pictures, and randomly dividing the pictures into a training set and a test set in proportion; 2, preprocessing the training set data; step 3, constructing a urine-8Net urine visible component identification network; 4, setting used network parameters; 5, training a urine-8Net urine visible component recognition model based on the urine8Net urine visible component recognition model in the step 3; and step 6, testing the obtained model by using the urinary sediment image test sets obtained in the step 1 and the step 2 to obtain an identification result and overall accuracy of the tubular components in the test set. According to the invention, image features can be automatically extracted, effective fine-grained recognition is carried out on selected urine visible components, the invention has the characteristics of high accuracy and high recognition speed, and the invention has a wide application prospect in clinical urinary sediment recognition and inspection.

Description

technical field [0001] The invention belongs to the field of medical image processing, in particular to a method for identifying transparent casts, pathological casts and mucus filaments in urine sediment. Background technique [0002] In clinical practice, urine sediment examination is a very common item. Urine sediment refers to the formed components obtained after centrifugation and sedimentation of relevant urine samples collected from the tested persons. By observing and analyzing the types and related quantities of these formed components, the doctor can judge whether there are related lesions in the urinary system of the tested person. Among them, the cast is formed by the condensation of proteins, cells and cell debris in the renal tubules, and the cast should not be found in the urine of normal people. According to the different components of casts, they can be divided into hyaline casts, granular casts, waxy casts, epithelial casts, red blood cell casts, and whit...
