Problems solved by technology
However, in the process of using spectral optical coherence tomography to obtain the image of the coating of the pill, the quality of the image of the coating of the pill has problems due to the influence of various noises introduced by the original spectrum.
In the traditional processing method of pill coating image, in order to eliminate the influence of various noises introduced by the original spectrum, by subtracting the reference light spectrum from the original spectrum, or subtracting the average value of the original spectrum, the noise introduced by the original spectrum cannot be completely eliminated. noise

Embodiment Construction
[0045] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0046] The pill coating image processing method provided by this application can be applied to such as figure 1 shown in the application environment. The terminal 104 receives the original spectrum sent by the pill detection device 102, the original spectrum is as figure 2 shown. The terminal 104 performs filtering processing on the original spectrum by using various filtering windows. The terminal 104 performs Fourier transform on the filtered spectrum to obtain a pill coating image. The terminal 104 classifies all the pixel points of the pill coating image to obtain...

A pill coating image processing method and apparatus, and a computer device and a storage medium. By means of receiving an original spectrum uploaded by a pill image detection device (302), using multiple types of filtering windows to carry out filtering processing on the original spectrum (304), carrying out Fourier transform on the filtered spectrum to obtain a pill coating image (306), classifying all pixel points of the pill coating image to obtain an impulse noise point set and a stable pixel point set (308), and carrying out de-noising processing on the impulse noise point set and the stable pixel point set to obtain a de-noised pill coating image (310), multiple types of noise introduced by the original spectrum can be eliminated. By means of carrying out de-noising processing on an impulse noise point set and a stable pixel point set, noise of a pill coating image can be eliminated, thus improving the quality of the pill coating image.
Description
technical field [0001] The present application relates to the technical field of image processing, in particular to a pill coating image processing method, device, computer equipment and storage medium. Background technique [0002] With the development of image processing technology, spectral optical coherence tomography technology has emerged. This imaging technology uses a camera to collect the original spectrum. After the original spectrum is Fourier transformed, the depth image of the object to be measured can be obtained. Fast speed, high signal-to-noise ratio, high resolution, non-invasive measurement, low cost and other advantages. However, in the process of using spectral optical coherence tomography to obtain the image of the coating of the pill, the quality of the image of the coating of the pill has problems due to the influence of various noises introduced by the original spectrum. In the traditional processing method of pill coating image, in order to eliminat...
