The invention also relates to a method for changing the visible eye color of a human eye, comprising the steps of preparing a pocket in the cornea of ​​the eye and inserting an implant into the corneal pocket, wherein the implant is configured as a corneal inlay comprising a colorant to simulate an iris, and a method for preparing a corneal inlay for a human eye, comprising the steps of providing a biocompatible base layer and applying a colorant to the base layer, wherein the colorant mimics the optical appearance of the iris of a human eye.

An object of a system according to an embodiment is to quickly diagnose a personal color of a user and propose appropriate fashion and color coordination.SOLUTION: A system includes a reception part, an analysis part, a diagnosis part, a proposal part, and an evaluation part. The receiving unit receives an image of a user. The analysis unit analyzes the image received by the reception unit and analyzes a face color, a hair color, and a pupil color of the user. The diagnosis unit diagnoses the personal color based on the information analyzed by the analysis unit. The proposal unit proposes fashion or color coordination based on the personal color diagnosed by the diagnosis unit. The evaluation unit evaluates the style proposed by the proposal unit.SELECTED DRAWING: Figure 1

The invention is an ocular device implantable in the human cornea using femtosecond laser assistance. It falls within the field of ophthalmic technology. It consists of the insertion of an intracorneal prosthetic iris implant, as shown in Figure 1, which could have both reconstructive applications (in the case of patients with iris defects) and aesthetic applications (reversibly modifying eye color).

The application discloses an eyeball depth image repairing method, system and device, and the repairing method comprises the following steps: acquiring an open-eye color image, an open-eye depth image, a closed-eye color image and a closed-eye depth image; respectively extracting key points from the open-eye color image and the closed-eye color image to obtain open-eye key point information and closed-eye key point information; respectively extracting depth information from the open-eye depth image and the closed-eye depth image according to the open-eye key point information or the closed-eye key point information to obtain open-eye depth information and closed-eye depth information; obtaining a position conversion matrix between the open-eye color image and the closed-eye color image according to the open-eye key point information and the closed-eye key point information; and obtaining an eyeball depth image of the repaired eyeball to be repaired according to the open-eye key point information, the open-eye depth information, the closed-eye depth information and the position conversion matrix. Through alignment and fusion of the closed-eye depth information and the open-eye depth information, the problem that the depth data is incomplete in an open-eye state is effectively solved.

The invention discloses an SSR (Simple Sequence Repeat) molecular marker primer group, a kit and a method for identifying spring dendrobium germplasm and application of the SSR molecular marker primer group. Belongs to the technical field of gene-assisted breeding. According to the invention, 15 pairs of SSR molecular marker primers are developed and screened from a dendrobium nobile transcriptome sequence for the first time, and the nucleotide sequences of the primers are shown as SEQ ID NO.1-30. The primer group is used for analyzing 128 parts of spring dendrobium germplasm, and genetic diversity evaluation, genetic relationship identification and population structure analysis can be effectively carried out. More importantly, through correlation analysis, it is found for the first time that multiple DoSSR1, 2, 3, 4, 6, 7, 10 and 14 markers are remarkably related to 13 key ornamental characters such as inflorescence stem length, flower number, petal color and labial lobe eye color, and an efficient and reliable tool is provided for spring dendrobium germplasm resource management, variety authenticity identification and molecular marker-assisted selection breeding.

This disclosure relates to methods for modifying the eye color of a subject by modulating the level and / or activity and / or stability of the OCA2 protein. This disclosure further relates to at least one OCA2 protein modifier or any composition containing the same, and the use thereof.

The application relates to a pigeon TYRP1 Mutant of a gene and application thereof, and belongs to the technical field of molecular biology. The nucleotide sequence of the mutant is shown as SEQ ID NO. 1. The application utilizes TYRP1 A frame shift mutation c.891delT (p.T297fs) of the gene has a double phenotype effect, so that it is possible to use eye color as a gender identification marker of white-feathered pigeons, and a bottleneck in application of feather color self-alternation technology in mainstream white-feathered breeds is broken.
