Problems solved by technology

On the other hand, using the extracted nail area images to make automatic nail machines will have a transformative impact on the nail industry
[0004] At present, there are few research results on the use of image segmentation to extract nail regions. Kumuda, N.S., and M.S.Dinesh ["Human fingernail segmentation."Emerging Research in Electronics, ComputerScience and Technology (ICERECT), 2015 International Conference on.IEEE, 2015.] proposed The method mainly realizes the extraction of nails based on color and the segmentation of each area of ​​the nail. This method only uses color information, which has great limitations and is not suitable for people with lighter skin.
Sun, Yu, et.al.["Estimation offeringertip force direction with computer vision."IEEE Transactions on Robotics25.6(2009):1356-1369.] The nail region extraction method used only uses the edge information of the nail, and the rough The stickiness is not high, and this method needs to carry out corresponding image calibration acquisition for each user's nail image in advance, and the practicability is poor

Embodiment 1

[0094] The present embodiment provides a method for extracting a nail image, which includes:

[0095] S10. When the user places the palm on the placing device according to the specified posture, acquire the hand image.

[0096] Specifically, the user places the palm of the hand on the placing device according to the specified posture. The user inserts the palm into the placing device according to the specified posture according to the prompt, wherein the specified posture is that the back of the hand is up, the five fingers are spread out, and the palm is close to the palm. The plane on which the tight-loading device is placed. After the user has placed the palm in place, an image of the palm is captured by the smartphone.

[0097] The placing device is a device for placing a palm so that a smartphone can take an image of the hand. The placing device includes a casing with an accommodating cavity, a placement plane is provided at the bottom of the accommodating cavity, and a...

Embodiment 2

[0115] In the nail image extraction method provided in this implementation, the intelligent terminal is directly used to extract the nails of the human hand, and the method specifically includes:

[0116] H10. The hand or foot to be analyzed is photographed by the intelligent terminal, and the hand image of the specified posture is obtained.

[0117] Specifically, when a user installs a specified gesture and places his hand on a plane, a guide map corresponding to the specified gesture is displayed on the smart device, and the user is prompted to adjust the position of the hand according to the guide map, so that all The imaging of the user's hand on the smart device is in the guide map, which can reduce the difficulty of image segmentation.

[0118] H20. Establish a classification model of the background of the hand image and the hand according to the contour information of the designated posture and the human skin information, and extract the palm image region according to t...

Abstract

The invention discloses a method and system for extracting a nail image. The method comprises the steps of: by machine vision equipment, carrying out shooting on a hand or foot to be analyzed so as to acquire an image of the hand or foot in a designated gesture; according to preset human skin color information, establishing a classification model of a background of the image and the hand or foot, and according to the classification model, extracting an image region of the hand or foot in the image; and according to the designated gesture, extracting a first nail region in the image region of the hand or foot, and extracting the nail image in the first nail region by adopting an image segmentation method. According to the method and system disclosed by the invention, the nail image is extracted according to outline feature information of human skin and nails under color features and in the specific gesture, so that both accuracy and robustness are greatly improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for extracting a nail image. Background technique [0002] Image segmentation technology is widely used in current commercial activities, including medical CT image analysis, mobile phone photography background blur, etc. Due to the ever-changing images, the image features in each field are different, so different fields need corresponding image segmentation techniques for processing. [0003] In the medical field, doctors can use the extracted nail images to prevent diseases. For example, if the nail meniscus is smaller than usual, it means that there is a problem with the current metabolism, and gray nails indicate that people have infectious diseases caused by fungi. The use of image segmentation technology to automatically extract nail regions and track the state of historical nails will play a certain early warning role in diseases, which is in ...
