In particle digital holography,the process of determing focal distance is cumbersome and complex using traditional numerical reconstruction methods.Based on Hilbert-Huang transform,a method for detecting axial position of particle from in-line digita

A method on particles holograms analysis was proposed based on Hough transform and linear chirp transform.Particles sizes were calculated using the position of minimum point in space domain and frequency domain.After pretreatment of noise reduction f
