The present invention relates to methods for the analysis of nucleic acids present in biological samples, and more specifically to normalize a high resolution melt curve to assist in the identification of one or more properties of the nucleic acids. The present invention provides methods and systems that incorporate a background identification algorithm according to invention principles using raw melt curve data to identify reactions that are unrelated actual DNA melt reactions. Furthermore, a web-based application for analyzing experimental data is provided. The raw experimental data obtained from a variety of instruments is processed and analyzed on a server and presented to a user through a user interface (UI).

Devices, systems, and methods obtain a first image, obtain a second image, calculate respective distances between a histogram from a patch in the first image to respective histograms from patches in the second image, and identify a patch in the second image that is most similar to the patch in the first image based on the respective distances.

Devices, systems, and methods for anomaly detection

SIFT features are selected from an input image. A SIFT procedure is applied to the input image to obtain candidate keypoints. For each candidate keypoint, there is calculation of a first Laplacian value (L) for pixels in an upper Scale Space and a second Laplacian value (L) for pixels in a lower Scale Space, based on the position of the candidate keypoint. A candidate keypoint is discarded if a Laplacian value Lof the keypoint position is less than or equal to either of Lor L. In the case that the candidate keypoint is not discarded, the candidate keypoint's Laplacian strength (L) is calculated, based on a relative change in Laplacian value from Lto Land from Lto L. One or more candidate keypoints are selected as SIFT features based on the corresponding Laplacian strength.

Selecting features from image data

Systems and methods for learning a high-level visual vocabulary generate inter-visual-word relationships between a plurality of visual words based on visual word-label relationships, map the visual words to a vector space based on the inter-visual word relationships, and generate high-level visual words in the vector space.

Systems and methods for generating a high-level visual vocabulary

Systems and methods for generating visual words define initial inter-visual word relationships between a plurality of visual words; define visual word-image relationships between the plurality of visual words and a plurality of images; define inter-image relationships between the plurality of images; generate revised inter-visual word relationships in a vector space based on the initial inter-visual word relationships, the inter-image relationships, and the visual word-image relationships; and generate higher-level visual words in the vector space based on the revised inter-visual word relationships.

Systems and methods for feature fusion

A method for establishing communication between a plurality of devices, including obtaining communication protocols that the plurality of devices support, determining which of the communication protocols are common to each the plurality of devices, determining operational parameters that are associated with each of the common communication protocols, indicating which of the common communication protocols and associated operational parameters can be used to establish communication between the plurality of devices, determining whether the plurality of devices can communicate with each other using the common communication protocols, and establishing communication between the plurality of devices using at least one of the common communication protocols.

Establishing communication between devices

Determination of locations of multiple rectangular areas within a composite projection area formed on a projection surface by a projector array of multiple projectors. A location of a maximum rectangular area is determined within the composite projection area. Available regions comprise regions unoccupied by previously-located rectangular areas. The maximum rectangular area is removed from the available regions. The following are iteratively repeated: determining a location of a next maximum rectangular area and removing the next maximum rectangular area from the available regions, until a stopping condition is met. A list of determined locations for rectangular areas within the composite projection area is provided after the stopping condition has been met.

Identifying multiple rectangular areas in a multi projector system

A centralization point in a projection area is designated. The projection area is on a projection surface onto which images are projected by a projector array, which includes a plurality of projectors. A first image is projected in a first maximum area rectangle at a first aspect ratio of the first image, and the first image is projected into the projection area centered at the centralization point. A second image is projected in a second maximum area rectangle at a second aspect ratio of the second image, and the second image is projected into the projection area centered at the centralization point.

Projector array for multiple images

A method and apparatus for printing over a network where a user at a client device is able to print to a network printer via a server device. The server device includes a print driver that initializes an asynchronous communication channel, sends notification message data to a client device over a network via the asynchronous communication channel, receives data from the client device in response to delivery of the notification message data, and requests user input data from the client device for printing.

Avoiding deadlock in network printing

A projector array includes a plurality of projectors, which together project images into a projection area on a projection surface. Aspect ratios are normalized for all of multiple images designated for display. The normalized aspect ratios are aligned at a common central point. An aspect ratio of a minimum rectangular shape is determined that will encompass all of the aligned aspect ratios. A maximum rectangular projection area is determined within the projection area having the same aspect ratio as the minimum rectangular shape. The center of the maximum rectangular area is designated as a centralization point. Each of all of the multiple images is sequentially projected into the projection area. Each image is scaled for display at its aspect ratio and is displayed centered at the centralization point.

Determining a rectangular area with a given aspect ratio within a global boundary formed by multiple projectors. An iterated process is repeated at moved locations along the global boundary, until a stopping condition is met. According to the iterated process, a point at a location of the global boundary is selected, a minimum rectangle with the given aspect ratio is grown from identified directions, and the largest rectangle encountered is delivered when the stopping condition has been met. For each such direction, the minimum rectangle is grown in the direction from the selected point until it intersects with a boundary, the grown rectangle is grown in another direction responsive to a determination that the grown rectangle can grow in another direction. The largest rectangle encountered previously is replaced, responsive to a comparison which indicates that the grown rectangle is larger than the largest rectangle encountered previously.

Identifying a rectangular area in a multi-projector system

Control of a multiprojector system having multiple projectors arranged in a projector array. It is determined whether the projector array is positioned to form one object or two or more objects. A first keystone correction mode is selected if it is determined that the projector array is positioned to form one object. A second keystone correction mode is selected if it is determined that the projector array is positioned to form two or more objects. In the first keystone correction mode, a homography transformation for each of the projectors is derived so as to accommodate keystone correction of all projectors in the projector array involved in the projection of the single object. In the second keystone correction mode, a homography transformation for each of the projectors is derived so as to accommodate keystone correction of all projectors involved in the projection of each object.
