A method and apparatus of detection, registration and quantification of an image. The method may include obtaining an image of a lithographically created structure, and applying a level set method to an object, representing the structure, of the image to create a mathematical representation of the structure. The method may include obtaining a first dataset representative of a reference image object of a structure at a nominal condition of a parameter, and obtaining second dataset representative of a template image object of the structure at a non-nominal condition of the parameter. The method may further include obtaining a deformation field representative of changes between the first dataset and the second dataset. The deformation field may be generated by transforming the second dataset to project the template image object onto the reference image object. A dependence relationship between the deformation field and change in the parameter may be obtained.

Generating a correction algorithm includes obtaining a model of an eye, the model including a front portion with optics to mimic a cornea and a lens of a human eye, and a rear portion having a generally hemispherical-shaped body to mimic a retina of the human eye. The rear portion includes physical reference lines on an inside surface of the generally hemispherical-shaped body. Images of the model are captured using an image capturing device aimed at the model. Vertices of the physical reference lines are identified according to a given projection technique for displaying generally hemispherical-shaped body in a two-dimensional image in the captured images. Idealized placement of the vertices of the physical reference lines is obtained according to the given projection technique. The result is a correction algorithm used to adjust any pixel of an image of an actual eye in the x-axis and in the y-axis.

A system and method for estimating dimensions of an approximately cuboidal object from a 3D image of the object acquired by an image sensor of the vision system processor is provided. An identification module, associated with the vision system processor, automatically identifies a 3D region in the 3D image that contains the cuboidal object. A selection module, associated with the vision system processor, automatically selects 3D image data from the 3D image that corresponds to approximate faces or boundaries of the cuboidal object.

The improved cuboidal dimensions are provided as dimensions for the object. A user interface displays a plurality of interface screens for setup and runtime operation.

A method of recording a medicament dose using a data collection device comprises capturing, by a video camera of said data collection device, a video showing a medicament dose indicator of a medicament delivery device, adjusting a scale of an image of said medicament dose indicator in said video, adjusting said image for skew of one or more characters displayed on a component of the medicament delivery device in said video, determining the position of at least one of said one or more characters in the image, identifying the at least one character using optical character recognition and determining a medicament dose shown by the medicament dose indicator based on a result of said optical character recognition. The method may include determining whether more than one delivery of medicament is recorded in the video and, if so, whether said more than one delivery includes one or more prime shots, so that an overall dosage delivered to a user may be determined based on multiple determined medicament doses. A wearable electronic device comprising a video camera may be used to obtain and analyse the video, for example, using software provided in an “app”. The wearable electronic device may be configured to be worn on the head of a user, to capture the video from the user's point of view.

The present invention concerns the field of stereoscopic vision systems and more particularly the management of the position of the focal plane in a stereoscopic scene. The invention aims to propose a method for managing the focal plane within a stereoscopic image or a sequence of stereoscopic images. A translation of the right and left images is effected in order to place the focal plane in front of the scene viewed. Advantageously, the depth of the major objects of the scene is estimated by a division of the images into a plurality of zones and estimation of the depth of each of the zones. The depth of the focal plane is then calculated so that most of the scene is behind the focal plane.

The display of correct and reliable operating image data which may change over the time is correctly and reliably displayed. A secured image is generated based on a source image by generating at least one secured image part.
