Filed:

Oct 21, 1999

Appl. No.:

09/422584

Inventors:

Matthew Robert Cole Atkinson - Cottage Grove MN

Assignee:

3M Innovative Properties Company - Saint Paul MN

International Classification:

G06K 946

US Classification:

382174, 382201, 382288

Abstract:

Patterns in an image or graphical representation of a dataset are identified through centroid integration. The image or graphical representation is digitized. A collapsed image is created by identifying the centroid and at least one characteristic value for each feature in the digitized image. A shape, such as a line, curve, plane or hypersurface, is stepped across the image. At each step, the characteristic values are summed for all centroids within a predetermined distance of the shape. Peaks in the resulting summation represent matches between the shape and a pattern in the data, with steeper peaks representing a better match. Different shapes, or the same shape at different angles, can be applied to the data to find better fits with the patterns in the image. The image can be multidimensional, with the shape being one dimension less than the image.

Appl. No.:

09/422535

Inventors:

Matthew Robert Cole Atkinson - Cottage Grove MN

Assignee:

3M Innovative Properties Company - Saint Paul MN

International Classification:

G06K 946

US Classification:

382174, 382201, 382288

Abstract:

A method and apparatus for identifying the orientation and positions of the elements of a grid in an image. The elements of the grid need not be parallel to the sides of the image, and the image need not contain all of the elements of the grid. The method can be applied to rectilinear and curved grids. The addresses of identified grid elements can be used to control, e. g. , analytical procedures directed to individual elements.

Abstract:

A method and apparatus for identifying the orientation and positions of the elements of a grid in an image. The elements of the grid need not be parallel to the sides of the image, and the image need not contain all of the elements of the grid. The method can be applied to multi-sided grids, whether rectilinear or distorted. The addresses of identified grid elements can be used to control, e. g. , analytical procedures directed to individual elements.

09/917545

Inventors:

Matthew Robert Cole Atkinson - Cottage Grove MN, US

Assignee:

3M Innovative Properties Company - St. Paul MN

International Classification:

G06T001/00

US Classification:

382272, 382271

Abstract:

The present invention provides to image processing methods that include a method of selecting an optimal threshold value (t) for an image comprising the steps of: obtaining an image; selecting a test segment of the said image; determining the mean feature size (S) of features appearing in the test segment at each of a plurality of threshold values (t), so as to produce mean feature size data (S(t)); selecting a relevant subset of the mean feature size data (S(t)); and determining an optimal threshold value (t) as a function of said subset of the mean feature size data. The present invention additionally provides methods of thresholding an image to produce a binary image by application of the optimal threshold value (t) determined according to the methods of the present invention.

International Classification:

A47L 13/16
A47L 17/08

Abstract:

A scrubbing article including a substrate, a stain release coating and a texture layer. The stain release coating is applied to the substrate and is present over a at least a major surface of the substrate, and the texture layer is formed over the stain release coating opposite the substrate. In some embodiments, the texture layer is printed on to the stain release coating. The substrate can assume various forms, such as nonwoven, fabric (e.g., woven or knitted), foam, film and sponge material or combinations thereof.

Abstract:

A scrubbing article including a substrate and a texture layer . The texture layer is formed on to a surface of the substrate and includes a multiplicity of microparticles. In some embodiments, the multiplicity of microparticles comprises plastic microbubbles and/or ceramic microspheres that are substantially spherical. In related embodiments, at least some of the ceramic microspheres are solid, and in other embodiments at least some of the ceramic microspheres are glass microbubbles. The substrate can assume various forms, such as nonwoven, fabric (e.g., woven or knitted), foam, film and sponge material or combinations thereof.

Abstract:

The curved cleaning element is made by providing a cleaning material with a back surface and a working surface that together define a volume and thickness. A portion of the cleaning material is removed at a pivot zone. The pivot zone separates the cleaning material into a first portion and second portion. At the pivot zone, the cleaning material has less thickness and/or less volume as compared to either the first or second portions. In one embodiment, the back surface of the first portion of the cleaning material is attached to a support and the second portion of the cleaning material is pivoted at the pivot zone. The second portion of the cleaning material is secured to either the support or the first portion of the cleaning material to form a continuously curving working surface of the cleaning material.
