For Segmenting An Image Patents (Class 382/171)
  • Patent number: 10043093
    Abstract: A supplemental device (2) for attachment to a pen-type drug injection device, the supplemental device comprising an optical sensor array or camera (25) configured to capture an image of one or more numbers representing dose values on a dose dial sleeve of the injection device, and a processor (24) and memory (240,241) arrangement configured to run an algorithm to receive image data from the sensor/camera and extract the dialed dose value from said image via optical character recognition (OCR). The algorithm is able to determine the set dose value which is at the centre of the image (902), also if the dose scale only comprises integer values in steps of two (see FIG. 9).

  • Patent number: 10019848
    Abstract: Techniques are disclosed for noise reduction and color smoothing of scanned 3D models for 3D printing. An anisotropic box kernel variant of a bilateral filter is applied to each vertex of a 3D mesh model, where the vertices contain color information. With bilateral filtering, the color at a given vertex is, under certain conditions, replaced by a Gaussian weighted average of colors of neighboring vertices. The weighting is a function of a geometric distance between vertices. The direction of traversal is limited towards neighboring vertices where a color mismatch is a color difference larger than the threshold value. The color of a neighboring vertex is rejected if the vertex normals differ from by a large angle. The weighted average of colors of the neighboring vertices is also rejected if the given vertex lies in a region where the color match/mismatch ratio is low at the end of the traversal.

Each error cost value comprises a cost value Cfb if segmentation decides on foreground for an element that should be background, and a cost value Cbf if segmentation decides on background for an element that should be in the foreground. Different areas of an image are estimated and error cost values assigned for a definite foreground (very high Cbf and very low Cfb), a definite background (very high Cfb and very low Cbf), an initial foreground (high Cbf and low Cfb), and an initial background (high Cfb and low Cbf). These error costs are utilized in combination with conventional segmentation decisions to modify those segmentation decisions and thus enhance segmentation accuracy.

    Abstract: A word segmentation method for segmenting a text line into word segments, which is particularly advantageous for processing italic text but can also be used for regular text. A horizontal center zone of the text line, corresponding to the vertical center parts of the characters, is used to generate a center-zone-only vertical projection profile. The center zone is determined using a horizontal projection profile, by locating the two major peaks of that profile and defining the two major peak positions as the upper and lower boundaries of the center zone. Spacing segments (white gaps) in the vertical projection profile are identified, and classified into two classes, namely character spacing (gap between characters with a word) and word spacing (gap between words). The word spacings are used to segment the text line into word segments.

    Abstract: Embodiments of the present invention provide concepts for correcting optical character recognition (OCR) errors from and OCR scan result by sequentially applying an anagram hash (AH) and Levenshtein-Distance (LD) measurement for concurrent character identity-based (machine code) and character shape-based (OCR-Key) corrections. The OCR-Key classifies characters by shape into one or more disjoint and overlapping classes. Similar shaped-based classes appearing in consecutive characters are appended to a cardinality term, a repetition count of the class. The LD measurement groups OCR-Keys and differentiates on both class and cardinality to arrive at a shape-based mismatch error between competing candidate words from an associated dictionary and a target word from the OCR scan.

An X-ray CT scanner (100) uses an X-ray detector (4), etc., to scan (F1) an object (3) to obtain X-ray transmission image data, and estimate (F3) an X-ray absorption coefficient distribution inside the object (3) based on the scanned X-ray transmission image data. Next, the X-ray CT scanner (100) performs a Monte Carlo simulation on a simulated object (3) having the X-ray absorption coefficient distribution estimated, and estimates (F4 and F7) a point spread function or scattered X-ray distribution derived from the object. Then, the X-ray CT scanner (100) corrects (F5 and F8), based on the point spread function or scattered X-ray distribution estimated, the X-ray transmission image data, and finally creates (F6 and F9) an image of the X-ray absorption coefficient distribution of the object (3).

  • Patent number: 8965123
    Abstract: A system and a method for identification of alphanumeric characters present in a series in an image are disclosed. The system and method captures the image and further processes it for binarization by computing a pattern of the image. The generated binarized images are then filtered for removing unwanted components. Candidate images are identified out of the filtered binarized images. All the obtained candidate images are combined to generate a final candidate image which is further segmented in order to recognize a valid alphanumeric character present in the series.

  • Publication number: 20150049944
    Abstract: Techniques are described for memory-efficient spatial histogram construction. A hierarchical spatial index has leaf nodes and non-leaf nodes, each leaf node representing a bounding region containing a spatial object, each non-leaf node representing a bounding region at least partially containing one or more spatial objects. A plurality of selected nodes is selected from the plurality of non-leaf nodes. The plurality of selected nodes includes an ancestor of each leaf node. For each particular node in the plurality of selected nodes, a weight is determined. The weight is based on the number of spatial objects contained within the bounding region of the particular node. A spatial partitioning of the plurality of selected nodes is determined. A spatial histogram is generated based on the spatial partitioning of the weights of the plurality of selected nodes.

The partitioning comprises assigning a color difference value to plurality of locations within the input image. The partitioning further comprises assigning each of the plurality of locations to an image region of the plurality of image regions, where the assigning occurs according to a particular order. The particular order is based at least in part on color difference values associated with the plurality of locations. The input image may comprise markup. Data representing at least a particular portion of the markup in the input image based on the partitioning is identified. Data representing at least the portion of the markup may be used in a visualization of a customizable product or a manufacturing control associated with a customizable product.

  • Patent number: 8928485
    Abstract: The present invention relates to the acquisition of tilted series images of a minute sample in a short time. The present invention relates to: measuring in advance the relation between an amount of focus shift and a degree of coincidence at the time of acquiring tilted series images; calculating backwards a focus shift from the degree of coincidence on the basis of this relation; correcting the focus shift by controlling a stage, an objective lens, and the like; and thus acquiring the tilted series images. In addition, the present invention relates to: acquiring a reference image in advance at the time of photographing the tilted series images; obtaining the correlation between an acquired image and the reference image; and performing, if the degree of coincidence is equal to or smaller than a set value, processing such as the transmission of a warning message and the stop of an image acquisition sequence.
