Cell segmentation
no vote
Principle: The job uses a global thresholding segmentation with Otsu method and two seeded region growing algorithm Design ideas: Read into the image, binary, image optimization (median filtering, holes filled, adhesion), saving pictures During this operation, the method is called in the Global_OTSU_Binarization.m file, called after Weiner before Adaptive Should be filtered to remove random noise, when used together with a correction factor to obtain the best results. In this work, region growing method is called in the RegionGrow.m file was selected when the actual use of a darker pixel of the picture top left as seeded region growing on negative inversion is the income after the end.

Synchronizing signal delay under conditions of pha
no vote
A set of single-phase controlled rectifier controlled by CPU is designed. Before entering the A / D port of single-chip microcomputer, the synchronization signal of power grid passes through two-stage operational amplifier and RC low-pass filter, resulting in a delay of 2 ms, which is equivalent to the phase angle lag of π / & lt; span style = & quot; font- size:10.5pt;font-family :"">5。 After the relationship between trigger angle and DC output voltage is obtained, in order to calculate the phase shift time T0, UK is quantified as an integer value of 0 ~ 128. According to the relationship between α - UD, the phase shift time TD can be solved and stored in the table

Defocus blur removal
no vote
For a pair of defocus type photos, choose the appropriate method to blur (1) the LAPLACE filter of fuzzy graph g, get x (2), to the autocorrelation of x to get o (3) o search corresponds to the minimum value of the ring in order to weaken the ringing effect, use the edgetaper function to blur image edges.
