Abstract (en)
[origin: WO2022136325A1] Method for characterising a travelling particle in a sample (10), the method comprising: a) acquiring at least one image (I o,n) of the sample during an acquisition period, using an image sensor (20), and forming a series of images, the series of images comprising at least one image; b) using each image in the series of images resulting from a) as the input image (I in,n) of a convolutional neural network for detection (CNNd), the convolutional neural network for detection being configured to detect the particles and to produce, from each image, an output image (I out,n) in which each particle detected is assigned an intensity distribution which is centred on the particle and extends around the particle; c) for each particle detected, from each output image (I out, n) resulting from b), estimating a position (xi, yi) of each particle detected in each image in the series of images; d) characterising each particle detected from the estimate of the position resulting from c), based on each image in the series of images.
