Dataset for calculating lattice vectors (and anisotropy) of zebrafish cone mosaic

This dataset contains images of UV cone nuclei near the retinal margin in live zebrafish. These UV cone nuclei are labelled by transgenic expression of a fluorescent reporter (that is photoconvertible).

The most important data are:
1. The zoomed-in (4X magnification) images of UV cone nuclei immediately after photoconversion
2. The zoomed-in (4X magnification) images of UV cone nuclei 2-4 days after photoconversion

Also included is code for segmenting UV cone nuclei (both in image from immediately after photoconversion and in image from days later) and for shifting and rotating the two images to maximally align corresponding UV cone nuclei. After aligning corresponding UV cones, we compute triangulations over UV cone nuclei positions (for both images) and identify bonds that are common to both images. We use these common bonds to calculate the lattice vectors for the UV cone lattice.

本数据集包含活体斑马鱼视网膜边缘附近的紫外（UV）视锥细胞核图像。此类紫外视锥细胞核通过可光转换荧光报告基因的转基因表达完成标记。

本数据集的核心数据包括：
1. 光转换后即刻采集的紫外视锥细胞核放大（4倍倍率）图像
2. 光转换后2至4天采集的紫外视锥细胞核放大（4倍倍率）图像

本数据集还附带用于分割紫外视锥细胞核的代码（涵盖光转换后即刻及数日后的图像），以及用于平移、旋转两幅图像以最大化对齐对应紫外视锥细胞核的代码。完成对应紫外视锥细胞核的对齐后，我们将对两幅图像中的紫外视锥细胞核位置进行三角剖分，并识别两幅图像共有的连接键。随后借助这些共有连接键计算紫外视锥晶格的晶格矢量。
