Skin Image Overlay and Matching Method for Efficiency Evaluation of Skin Products, Cosmetics, Foods, Medical Supplies

摘要

The present invention can be seen by overlaying skin imaging for the measurement and determination of the skin to improve product efficacy, skin improvement effect on skin image matching method and the characteristics of the already extracted from the input image and the current camera image obtained by calculating an error between these automatically through the overlay to obtain an image in the correct position by adjusting the position of the specimen during the measurement relates. ; skin through the overlay image matching method of the present invention is applied to the sample input in real time via the camera after a translucent screen to adjust the alpha value of the entire skin, apply image skin image stored in DB After the overlay that: (a) in skin imaging; The skin around the image and then apply the application by setting the threshold value by comparing the histogram for each image of the skin to remove the noise through the morphological processing after conversion into a binary image and performs preprocessing to connect the disconnected regions (b) steps; After the application before applying to the skin image and the feature extraction to extract the pore region and the location point for each of the skin image comparison step (c); Calculating a position error of the skin image and the application before the application to the skin image and the distance calculation between the extracted position compare points (d) and the applying step and the skin around the image by moving the specimen in accordance with the position error After applying comprises the step of accurately matching the skin image.
