Biological analysis system function:

1. The basic module: image acquisition, processing, geometric measurements, fixed-fold printing, image splicing and other basic functions;

2.Optional modules:

2.1 Colony analysis: can analyze the long axis, short axis, diameter, area and calculate the statistics of each colony and the maximum area of the colony parameters, analyze the particles inside the larger colony,;

2.2 Cell analysis: can analyze the long axis, short axis, perimeter, area of each cell and calculate the statistics of the cell and the parameters of the largest area of the cell;

2.3,Image superposition: search out the contour of the observed object on the first biological image, and then load the second image, the software projects the contour lines searched out in the first image onto the second image, and at the same time calculates the parameters such as the long axis, short axis, perimeter, area, number of pixels, average gray scale of the projection range of each contour line, and automatically calculates the parameters within the superposition interval;

2.4. Immunohistochemistry: extract the basic color of each component and set the tolerance range, the software searches out the area, percentage, number of particles, average gray level and other parameters corresponding to the component on the image, and can analyze 8 kinds of components at one time;

2.5 Component analysis: extract the basic color of each component and set the tolerance range, the software searches out the area, percentage, number of particles, average grayscale and other parameters corresponding to the component on the image, and can analyze 40 kinds of components at one time;

2.6 Particle analysis: extract the basic color of the particles, set the tolerance range, and the software searches out the long axis, short axis, diameter, area, peripheral color and other parameters corresponding to the component on the image;
