Deformation tracking
WebSep 22, 2024 · Compared to SPR, cell edge deformation tracking can not only measure the whole-cell response (not limited to the bottom portion of the cell) but is also able to measure small-molecule binding kinetics [7,8]. This is important because most drugs are small molecules. Complementary to edge tracking, SPR imaging provides both binding … WebMay 16, 2024 · The flowchart of deformation monitoring based on computer vision is shown in Figure 1, and can be summarized as follows: (1) assemble the camera and lens to aim at artificial or natural targets, and then acquire images; (2) calibrate the camera; (3) extract features or templates from the first frame of the image, then track these features again ...
