A device () and method for controlling a camera () are provided. The device comprises an input unit () configured to obtain video data from the camera; an image processing unit () configured to determine from the obtained video data if a particular person is present alone in a first area monitored by the camera; a control unit () configured to generate a control signal for controlling the camera to operate in a first monitoring mode or a second monitoring mode based on the determination by the image processing unit if the particular person is present alone in the first area monitored by the camera; and an output unit () configured to output the control signal to the camera.

An ultrasound transducer unit (), e.g. probe, is configured with a friction guiding function. The transducer unit () comprises a vibration generating means () at a tissue contact area, and has means for sensing a sliding direction of the transducer unit across a tissue surface () at which the contact area is incident. The tissue surface may be an external skin surface or an internal tissue surface, e.g. in case of a catheter. A control means is operable to control the vibration of the vibration generator to adjust a level of friction at the tissue contact area. This is used by the control means to implement a friction guiding function for guiding a user in sliding the unit across the incident surface, e.g. toward a target location (), based on controlling the friction level responsive to sensed sliding direction, for instance providing lower friction when sliding is in a target direction, while leaving other directions with relative higher frictional resistance.

Currently, there is interest in applying machine learning techniques to analyse digital pathology images automatically. Machine learning techniques often rely on training with a ground-truth image input. The quality and amount of training data determines the quality of the detector, as expressed in the rate of true and false positives, and robustness against variations in the appearance of the input images. The present application proposes to obtain image data of the same sample before and after at least one re-staining step (firstly with a structure-revealing stain, and secondly with a bio marker revealing stain). Sections of the first and second image data having a good registration relationship are chosen, along with the probability of detecting a desired candidate object (such as nucleus) and the probability of the bio marker revealing stain being present annotation data suitable for training a machine learning algorithm on the first and/or the second image data is provided.

The invention relates to a printing control device () to control printing of a cover layer on a tissue or cell sample to be examined, a system () for printing of a cover layer () on a tissue or cell sample to be examined, a method to control printing of a cover layer on a tissue or cell sample to be sample to be examined, a computer program element for controlling such device or system for performing such method and a computer readable medium having stored such computer program element. The printing control device () comprises an imaging unit () and a printing control unit (). The imaging unit () is configured to provide image data of the sample, and to determine a local image parameter from the image data. The local image parameter relates to local tissue porosity and/or a local capillary force of the sample. The printing control unit () is configured to control a printing parameter for printing the cover layer on the sample based on the local image parameter.

A monitoring apparatus for monitoring an ablation procedure applied to an object comprises an ultrasound signal providing unit for providing an ultrasound signal. The ultrasound signal is produced by sending ultrasound pulses out to the object, by subsequently receiving dynamic echo series after the ultrasound pulses have been reflected by the object, and finally by generating the ultrasound signal depending on the received dynamic echo series, whereby ultrasound scattering properties of the object are determined that represent blood perfusion. The monitoring apparatus further comprises an ablation depth determination unit for determining an ablation depth from the provided ultrasound signal.

The invention relates to an imaging system for imaging a periodically moving object. An assigning unit () assigns ultrasound signals like A-lines to motion phases based on a provided phase signal, wherein an ultrasound images generation unit () generates several ultrasound images like gated M-mode images for the different motion phases based on the ultrasound signals assigned to the respective motion phase. A selecting unit () is used to select an ultrasound image from the generated ultrasound images, wherein a display unit () displays the selected ultrasound image. The selected ultrasound image corresponds therefore to a single motion phase only such that motion artifacts in the displayed ultrasound image are reduced. The imaging system is particularly useful for, for instance, monitoring cardiac ablation procedures.

An assigning unit () assigns ultrasound signals like A-lines to motion phases based on a provided phase signal, wherein an ultrasound images generation unit () generates several ultrasound images like gated M-mode images for the different motion phases based on the ultrasound signals assigned to the respective motion phase. The ultrasound images are temporally consecutively displayed on a display unit () for showing the periodic movement of the object (). The resulting dynamic, movie-like image of the object allows a user like a physician to more reliably determine properties of the object like a thickness of a tissue wall, in particular, during an ablation procedure. The imaging system is therefore particularly useful for monitoring cardiac ablation procedures.

Clusters of pixels are defined for image compression and decompression. The image information used to define the clusters may include pixel values at predetermined positions relative to a pixel or related motion vectors, gradients, texture etc. During compression of images, image information relative to pixels is examined to determine the cluster to which it belongs. Thus pixels can be classified according to the cluster for their image information. In an embodiment the definitions of the clusters are selected dynamically, dependent on image content. For each cluster a control parameter set is computed for a post-processing operation, such as filter coefficients for filtering or statistical data for locally generating texture. The control parameter set is selected dependent on the image content so that, when the post-processing operation is applied to the image after decompression it will improve image quality for the pixels that are classified as belonging to the cluster.

Image compression and decompression

The invention relates to an apparatus for being used for detecting a property of an object. An ultrasound signal providing unit () provides an ultrasound signal, which is indicative of a property of the object () at one or several depths within the object () and which depends on time, and a periodicity value determination unit () determines a periodicity value being indicative of a degree of temporal periodicity of the ultrasound signal for a constant depth. The temporal periodicity of the ultrasound signal at the respective constant depth, i.e. the periodicity value, depends on the property of the object at this depth and can therefore be used for detecting a property of the object.

The control parameter set is selected dependent on the image content so that, when the post-processing operation is applied to the image after decompression it will improve image quality for the pixels that are classified as belonging to the cluster. The compressed image and the control parameter sets are transmitted to a decompression apparatus. Upon decompression, the image information that represents the decompressed image is examined to classify pixels according to the clusters and the different control parameter sets for the selected clusters are used to control post-processing at the locations of the pixels.
