  • Publication number: 20240362791
    Abstract: The present disclosure relates to systems, non-transitory computer-readable media, and methods for utilizing machine learning to generate a mask for an object portrayed in a digital image. For example, in some embodiments, the disclosed systems utilize a neural network to generate an image feature representation from the digital image. The disclosed systems can receive a selection input identifying one or more pixels corresponding to the object. In addition, in some implementations, the disclosed systems generate a modified feature representation by integrating the selection input into the image feature representation. Moreover, in one or more embodiments, the disclosed systems utilize an additional neural network to generate a plurality of masking proposals for the object from the modified feature representation. Furthermore, in some embodiments, the disclosed systems utilize a further neural network to generate the mask for the object from the modified feature representation and/or the masking proposals.

  • Patent number: 11848172
    Abstract: The present invention relates to a method for measuring a sample with a microscope, the method comprising scanning the sample using a focusing plane having a first angle with respect to a top surface of the sample and computing a confidence distance based on the first angle. The method further comprises selecting at least one among a plurality of alignment markers on the sample for performing a lateral alignment of the scanning step and/or for performing a lateral alignment of an output of the scanning step. In particular, the at least one alignment marker selected at the selecting step is chosen among the alignment markers placed within the confidence distance from an intersection of the focusing plane with the top surface.

  • Patent number: 10410828
    Abstract: Disclosed is a charged particle beam system comprising a charged particle beam column having a charged particle source forming a charged particle beam, an objective lens and a first deflection system for changing a position of impingement of the charged particle beam in a sample plane. The system further comprises a sample chamber comprising a sample stage for holding a sample to be processed, and a controller configured to create and store a height map of a sample surface. The controller is further configured to dynamically adjust the objective lens of the charged particle beam in dependence on a position of impingement of the charged particle beam according to the height map.

  • Patent number: 5255330
    Abstract: A facility is provided which determines the optimum phase of a sample clock signal that is used to acquire a copy of an image containing text. In particular, the phase of the sample signal is set to an initial value and is thereafter incremented by a predetermined amount of time following the acquistion of each of a predetermined number of copies of the image, in which each such copy is defined by respective pixel values. Upon acquiring a current copy of the image, a histogram is formed from ones of the pixel values and is stored in memory in place of a priorly stored histogram if the latest histogram contains more pixel values indicative of text than the priorly stored histogram. The phase of the sample clock signal is then adjusted to the phase associated with the histogram that is stored in memory following the last of such acquisitions.
