Title:
IMAGE DETECTION METHOD AND APPARATUS, COMPUTER DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/205290
Kind Code:
A1
Abstract:
An image detection method and apparatus, a computer device, and a storage medium. The image detection method comprises: obtaining an original finger vein image from a collection device (S1); performing a Gabor wave transform on the finger vein image to obtain an enhanced image (S2); performing binarisation processing on the enhanced image to obtain a binarised image (S3); performing expansion processing on the binarised image to obtain an expanded image (S4); identifying finger vein lines in the expanded image, and performing deletion processing on the finger vein lines to obtain a denoised image (S5); identifying finger edge lines in the denoised image, and performing extension processing on the finger edge lines to obtain a complete finger edge image (S6). The present invention accurately positions finger edges, thereby effectively increasing the accuracy of detecting finger edges in finger vein images, as well as improving the applicability to various different finger vein collection devices.
