  • Publication number: 20180187256
    Abstract: The present disclosure discloses a method for controlling a base sequence determination, a base sequence determination system, and a control device. The base sequence determination system includes a fluid device and an optical device, a reaction device includes a first component and a second component, and a repeated executable unit included in the base sequence determination is defined as: a second biochemical reaction—a first biochemical reaction—photographing. The method includes, after initiation steps are completed, using the fluid device to perform the second biochemical reaction and the first biochemical reaction of the sample on the first component, while using the optical device to photograph the sample on the second component. The initial steps include: a. using the fluid device to perform the first biochemical reaction of the sample on the first component, b. using the optical device to photograph the sample on the first component after the first biochemical reaction, and c.

  • Publication number: 20180101951
    Abstract: The present disclosure provides a method and a system for processing an image. The method includes: an image pre-processing step, including analyzing an image input to be processed so as to obtain a first image; and a spot detecting step, including analyzing the first image so as to compute a spot determining threshold; analyzing the first image so as to acquire a candidate pixel spot, and judging whether the candidate pixel spot is the spot according to the spot determining threshold; computing a sub-pixel center coordinate of the spot and an intensity value of the sub-pixel center coordinate if yes; and discarding the candidate pixel spot if no. According to the method, the image is denoised in the image pre-processing step, such that a calculation in the spot detecting step may be reduced. In addition, the accuracy of determining the image spot may be improved.
