- the invention comprises a computer-implemented method for reducing a data volume of images to be stored in an image acquisition sequence of a patient, comprising the steps:
- Image recordings of an image recording sequence are images of physical structures that were recorded by a photo camera and/or a video camera. Such image recordings have an image resolution that is linked to a number of pixels of the recording device (photo camera and/or video camera).
- the image recordings have image noise and other image artifacts and generally quality limitations. These are linked to the recording technology (performance of the camera and/or video camera) and are also referred to as interference signals.

- Super-resolution essentially refers to methods for image processing that increase the resolution of an image.
- Super-resolution image processing essentially involves increasing the number of pixels in an image by interpolation, which creates new pixels.

- the burst image processing device, the super-resolution image processing device and the image compression device can execute or be designed as a software, an app or an algorithm with different data processing capabilities. These devices can be implemented in hardware and/or software, wired and/or wireless and in any combination thereof. They can also include an interface to an intranet or the Internet, to a cloud computing service, to a remote server and/or the like.
- the provision device can have various sensors that can capture (or record) images. Furthermore, the provision device can receive, process and evaluate sensor data.
- the computer-implemented method according to the first aspect of the invention can be carried out with the system according to the second aspect of the invention.

- the invention provides a computer program product comprising an executable program code which, when executed, is adapted to carry out the method according to the first aspect of the present invention.
- the invention provides a non-transitory computer-readable data storage medium comprising executable program code adapted to perform the method according to the first aspect of the present invention when executed.
- the non-volatile, computer-readable data storage medium may comprise or consist of any type of computer memory, in particular a semiconductor memory, such as a solid-state memory.
- the data storage medium may also comprise or consist of a CD, a DVD, a Blu-ray disc, a USB memory stick or the like.
- the invention provides a data stream which comprises or is adapted to generate an executable program code which, when executed, is adapted to carry out the method according to the first aspect of the present invention.
- One idea underlying the invention is to introduce a computer-implemented method with which image recordings and in particular video recordings could be stored (or transmitted) with a reduced data storage space.
- the reduction is achieved by combining two effects:
- artifacts e.g. caused by hardware limitations
- This is done, for example, by using burst image processing.
- the method can be used in two modes.
- a first mode the pre-processed images are compressed and then processed using super-resolution.
- the super-resolution is then carried out as post-processing, which can be carried out, for example, during the visualization of the video recording.
- a second mode the pre-processed images are processed using super-resolution and then compressed.
- the compressed file package contains super-resolution images and no post-processing is required.
- the system comprises a provision unit by which images of a medical activity or scene are captured (for example if the provision device comprises the camera of an endoscope) or read in (for example if the captured images were received from the camera of an endoscope).
- a burst image processing device is used to carry out image processing that generates denoised (or interference-free) images (images with reduced image artifacts) based on combinations of the images.
- a super-resolution image processing device is used to generate super-resolution images using super-resolution.
- An image compression device is set up to compress the images generated by the burst image processing device or the images generated by the super-resolution image processing device.
- One advantage of the present invention is that the combination of burst image processing and super-resolution image processing significantly reduces the amount of data in the image recordings, without any loss in the useful signal.
- the removal of image noise and/or various image artifacts ensures that the compression essentially only affects the useful signal, which serves to achieve higher compression factors.
- the super-resolution ensures that the resolution of the denoised image recordings is increased. The result is a high-resolution video recording with good image quality and low storage requirements.
- Another advantage of the invention is that a better low-light performance can be achieved. This allows for a gentler treatment of the patient by using thinner endoscopes with smaller camera lenses can be used for medical/surgical activities.
- a further advantage of the invention is that the increase in image quality and image resolution of the processed video recordings is not related to the hardware of an endoscope.
- the invention is achieved by optimizing data processing and does not require any improvement in the hardware.
- the light-dark contrast is particularly strong in endoscopic image recordings. It is therefore advantageous to be able to work with underexposed raw images. Undesirable effects such as image noise or motion blur can be minimized and filtered and removed using burst image processing. This helps to improve low-light performance.
- the computer-implemented method further comprises storing the compressed generated high-resolution and/or the compressed generated preprocessed image recordings of the image recording sequence.
- the data can be stored after compression and kept in a computer, in a server or in a cloud computing platform.
- the compressed files can have at least one identifier that indicates whether the file contains compressed generated preprocessed image recordings or compressed generated high-resolution image recordings.
- the generation includes reading in the stored compressed, generated preprocessed images of the image recording sequence.
- the reading in can be carried out using an interface which, for example, has the super-resolution image processing device. This allows the stored file to be retrieved and processed for visualization with increased resolution.
- the generation of the preprocessed image recordings of the image recording sequence by means of burst image processing comprises the following steps:
- Burst image processing produces images with a variety of details of the recorded physical structures.
- the images produced are based on a combination of signal information from a sequence of images arranged one after the other in time.
- Burst image processing can be performed using a burst algorithm. Accordingly, the images are first grouped, bundled, or clustered. The number of images in each group depends on the image capture rate (the number of frames captured per second), which in turn depends on the camera. Typically, a group can contain between 3 and 20 images. The different images in each group are then segmented. The size of the image segments can vary. An image segment can contain one pixel, but also a large area of an image. The segments of an image do not have to be the same. It is important that spatially correlated segments of the different images in a group are comparable so that they can be combined in a processed image segment.
- the processed image segments create a processed image.
- the number of corresponding spatially correlated image segments that are combined to form a preprocessed image recording depends on the brightness of the corresponding image segments.
- the processed image capture can be generated more quickly by making the overlap of the image segments dependent on the brightness of the image segments.
- the brightest image segment can use only the last image capture (in a temporal order of the image captures) of the image capture group, while the darkest image segment can use all of the image captures of the image capture group.
- the combining of corresponding spatially correlated image segments comprises:
- the overlapping of the various image segments of an image acquisition group can involve at least three steps: First, an alignment of the image segments, which can be carried out, for example, with regard to pixel identification. The image segments are then merged or superimposed. This can be done adaptively by carrying out the superimposition step by step. For example, in an image acquisition group with 20 images, the superimposition can be carried out with only 4 images at a time. When the fifth image has been taken, the first image is no longer taken into account so that the algorithm always works with 4 images at the same time. The superimposition serves to filter out image noise.
- Color tone mapping refers to various image processing methods, such as black level subtraction, white balance, Bayer demosaicing, bilinear chroma denoising, sRGB color correction, tone mapping, gamma correction, global contrast adjustment and unsharp mask sharpening, and/or correction of chromatic aberrations.
- the generation of a high-resolution image recording by means of super-resolution image processing with the aid of a trained Artificial intelligence model wherein the trained artificial intelligence model corresponds to a convolutional neural network, CNN, or a deep learning architecture, in particular a transformer-based architecture, or the like.
- Super-resolution image processing essentially involves increasing the number of pixels in an image using an interpolation algorithm that generates new pixels.
- This interpolation algorithm can be implemented with an artificial intelligence model or at least partially supported by it.
- Particularly suitable models are artificial intelligence models that have been adapted for pattern recognition. These include CNNs in particular.
- Models with vision transformer (ViT)-based architectures, such as a Swin transformer, are becoming increasingly important. This means that the generated images can be created with a resolution four times higher than the resolution of the raw images, for example.
- ViT vision transformer
- the burst image processing device comprises a calculation unit which implements a burst algorithm which is designed to recognize fine physical structures such as veins and nerves in the images provided in the image recording sequence of the patient.
- a burst algorithm which is designed to recognize fine physical structures such as veins and nerves in the images provided in the image recording sequence of the patient.
- the burst image processing device is adapted to achieve recognition of fine structures. This is implemented by recognizing these structures via the image recording sequence of an image recording group during their movements and enhancing them with a color contrast so that the processed images generated represent these fine structures with satisfactory image quality.
- the provision device of the system is integrated in an endoscope or in an exoscope.
- the provision device can comprise the video camera of an endoscope or exoscope and/or other image sensors that are present in an endoscope or in an exoscope.
- the burst image processing device and/or the super-resolution image processing device can be implemented in the data processing device of an endoscope or an exoscope, which processes the signals from the camera of the endoscope/exoscope to create visualizable images.
- the system further comprises a data storage device in which the image recordings of the image recording sequence compressed by the image compression device are stored and from where they can be read out.
- the data storage device can store the compressed generated processed image recordings and/or the compressed generated high-resolution image recordings.
- the system further comprises a video interface which is designed to transmit the generated preprocessed image recordings of the image recording sequence and/or the generated high-resolution image recordings of the image recording sequence to a display unit of the system.
- the system can allow a user to visualize the processed image recordings, either after burst image processing or after super-resolution image processing, in a display. If the image recordings are processed real-time image recordings that originate directly from the video camera of an endoscope, at least the burst image processing device and the super-resolution image processing device can advantageously be implemented in the display unit of the endoscope.
- facilities Although some functions are described here and below as being performed by facilities, this does not necessarily mean that these facilities are provided as separate entities. In cases where one or more facilities or a part thereof are provided as software, the facilities may be implemented by sections or snippets of program code that may be separate from each other, but may also be interwoven or integrated with each other.
- the functions of one or more devices may be provided by one and the same hardware component, or the functions of several devices may be distributed across several hardware components that do not necessarily correspond to the devices. It is therefore to be assumed that any application, system, method, etc. that has all the features and functions attributed to a particular device comprises or implements that device. In particular, it is possible that all the devices are implemented by program code executed by, for example, a server or a cloud computing platform.

- the image segments of an image recording do not have to be the same size.
- the image segments should ensure that all details and properties of an image recording are optimally identified. Areas of an image recording that look homogeneous can, for example, be associated with or displayed with an image segment. Areas of an image recording with different details usually require more than one image segment. It is advantageous if locally correlated image segments of the various image recordings of an image recording group are of comparable size.
- step S22 the number of locally correlated image segments can depend on the brightness of the corresponding image segments.
- step S22 the spatially correlated image segments are combined to form a corresponding preprocessed image recording. According to the embodiment of Fig. 1, step S22 comprises steps S221, S222 and S223.
- step S221 an alignment of the image segments is carried out, which can be carried out, for example, with regard to pixel identification.
- step S222 the image segments are merged and/or superimposed. This can be done adaptively by carrying out the superimposition step by step.

- the embodiment of the invention shown in Fig. 2 can be advantageous for further reducing the storage space requirement.
- the super-resolution is carried out as a post-processing of the image recordings during the visualization of the video file.
