Embodiments include systems and methods for generating a data throughput estimation model. A system may be monitored to measure both (a) data throughput and (b) computing statistics of one or more computing resources to generate an initial data set. The relationship between the data throughput and the computing statistics, in the initial data set, is used to generate a data throughput estimation model. The data throughput estimation model may be generated using a machine learning model, a neural network algorithm, boosting decision tree algorithm, and/or a random forest decision tree algorithm. Additional measurements of the computing resource statistics may be applied to the data throughput estimation model to estimate data throughput.

Predicting application performance from resource statistics

A method, apparatus and computer program product for providing Global Account Lockout (GAL) using an Ordered Messaging Service (OMS) is presented. A database operation is received from a client, and a determination made regarding whether the operation contains an authentication mechanism. When the operation does not contain an authentication mechanism, then the operation is returned from. When the operation does contain an authentication mechanism, then the following steps are performed: locating the entry and checking its authentication mechanism, determining whether the authentication mechanism in the operation is good, sending a bind message to a GAL manager, checking and updating GAL state, committing updates to GAL state, and returning operation to the client.

Global account lockout (GAL) and expiration using an ordered message service (OMS)

A method and computer program product for providing Global Attribute Uniqueness (GAU) using an Ordered Message Service (OMS) is presented. A database operation is received from a client. A determination is made regarding whether the operation changes a value to a current value and when the operation would change a value to a current value then operation is ended. When the operation would not change a value to a current value the operation is decomposed into ADD messages and DELETE messages. The ADD messages are sent to a GAU manager and GAU state is checked and updated. The updates are committed to GAU state and the Directory Server (DS) is updated. Operation is then returned to the client. DELETE messages are sent to the GAU manager and GAU state is updated. The updates are then committed.

A method for modeling a database management system involving receiving a query, computing a hit rate value associated with a cache, wherein the hit rate value is computed using a counter group, comparing the hit rate value to a predetermined value to obtain a result, providing a reply to the query if the result is a hit, incrementing a counter in the counter group when the cache is not full and proceeding to a next cache if the result is a miss, and providing a diagnostic output for the database management system.

Cache abstraction for modeling database performance

A method for the encryption and decryption of digital images based on cyclotomic polynomials and radiometric expressions comprising the steps of generating an encrypting transform, partitioning the digital images into data blocks, along with encrypting, transmitting, and decrypting the data blocks. Three common radiometric expressions are fundamental metamers, black metamers, and radiometric functions. In one embodiment, the mathematical equation that represents the encrypting transform is a cyclotomic polynomial. In another embodiment, a cyclotomic polynomial is used to calculate the coefficients of the mathematical equation that represents the encrypting transform. In other embodiments, the encrypting transform is generated with a radiometric expression, and the encrypted data blocks are calculated with a radiometric expression.

Cryptographic method for color images and digital cinema

A method and apparatus for selectively applying image enhancement processing to parts of an image. In one embodiment, spatial processing transformations, such as sharpening for example, are reduced or bypassed for pixels having color code values within a range known to be adversely affected by the spatial processing transformations. In another embodiment, color correction processing transformations are bypassed for pixels having color code values within a neutral color range. These neutral colors may have a gray-correction transformation applied in order to better separate the neutral colors from the other colors. According to another embodiment, color code values for pixels are transformed to two or more different color spaces. If a color correction transformation will have adverse affects on a pixel in one color space, corrected data from a different color space can be utilized for the pixel.

Method and system for selective enhancement of image data

One aspect of the invention is a method for locating an unexposed region of film. The method includes the step of illuminating film with a light source while the film has developing chemical applied thereto, the film comprising at least two edges along an x direction perpendicular to a y direction parallel to a surface of the film. The method also includes the step of identifying an unexposed region of the film as a region containing ones of a first plurality of columns of the film, the columns disposed generally in the y direction and captured using at least one sensor operable to capture light reflected from the film, and wherein a representative value for each of the ones of first plurality of columns exceeds a threshold.

Digital film processing feature location method and system

One aspect of the present invention is a system for estimating sensor and illumination non-uniformities. The system comprises a first light source, and a first sensor operable to capture light reflected from a first side of film illuminated by the light source while the film has a developer chemical applied thereto and processing circuitry coupled to the first sensor. The processing circuitry is operable to capture a first plurality of readings from the sensor responsive to light reflected from an unexposed region of film to determine a first set of non-uniformity data and adjust image data obtained from the film in response to the first set of non-uniformity data. In a further embodiment, the processing circuitry is further operable to dim the first light source for at least a portion of the time that the sensor is being used to sense the unexposed region of the film. The processing circuitry may also capture a second plurality of readings from the sensor while the first light source is dimmed to determine a second set of non-uniformity data and adjust image data obtained from the film in response to the second set of non-uniformity data.
