Embodiment Construction

[0075] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0076] figure 1 The flow chart of the method for selecting the best urine sediment microscope image provided by an embodiment of the present application, the specific steps are as follows:

[0077] Step 101: For a collected urine sediment sample, collect multiple urine sediment images of the sample by fine-tuning the lens of the microscope.

[0078] Here, the level of "fine-tuning" is usually on the order of microns.

[0079] Step 102: For each urine sediment image, detect all urine cells in the image.

[0080] Step 103: For each detected urine cell, perform high-pass filtering on the urine cell to obtain the spectral energy of the urine cell.

[0081] Step 104: Calculate the spectral energy mean and variance of the ima...

Abstract

The invention relates to a method and device for selecting a urinary sediment microscope image with optimal focusing performance. The method includes the following steps that: a plurality of urinary sediment images of one urine sediment sample are acquired through the lens of a fine-tuning microscope; all urine cells in each urinary sediment image are detected, high-pass filtering is performed on each detected urine cell, so that the spectrum energy of the urine cells can be obtained, and the mean value and variance of the spectrum energy of each image are calculated; and based on a rule that the larger the mean value of spectrum energy is, the smaller the variance of the spectrum energy is, and the better the focusing performance of an image is, an image with optimal focusing is selected from the plurality of urinary sediment images. With the method and device of the invention adopted, it can be ensured that a finally-selected image is an image with optimal focusing.

Description

technical field [0001] The present application relates to the technical field of image analysis, and in particular, to a method and device for selecting a urine sediment microscope image with the best focus. Background technique [0002] Urinalysis is a common and important test. After a urine sediment sample is collected, an image of the urine sediment is taken under a microscope in order to show the urine cells more clearly. In order to ensure the collection of clear urine sediment images, usually for a urine sediment sample, multiple urine sediment images are collected by fine-tuning the lens of the microscope, and then the clearest image is manually selected for the next step of detection and analysis. [0003] Manual selection of the clearest urine sediment image is susceptible to subjective influence. SUMMARY OF THE INVENTION [0004] Embodiments of the present application provide a method and apparatus for selecting a urine sediment microscope image with the best ...
