    摘要: A method for automated classification of curve patterns associated with dynamic image data of a lesion in a subject in order to determine characteristics of the lesion. The method comprising the steps of loading the image data into an electronic memory means, producing a plot of signal intensity profile, converting the signal intensity profile into a contrast enhancement profile, detecting a reference enhancement profile having a highly positive slope over an initial enhancement period followed by a decreasing profile portion, deriving signature curve types based on the reference enhancement profile, classifying an enhancement curve for each pixel in a selected ROI into one of the derived signature curve types using all available time points and displaying a grid-plot of the classified enhancement curves for all pixels in the selected ROI, wherein the overall display of curves and heterogeneity provides visual indication of the characteristics of the lesion.

    摘要: A set of similarity detection algorithms and techniques for determining which signature calculation, sampling, and generation algorithms may be most beneficially applied to application related data are described herein. These algorithms work well with SSD caching software to product high speed, high accuracy, and low false-positive detections. Because the different algorithms may show different performance depending on data sets and different applications, to achieve optimal performance, a calibration process may be applied to each application and associated data set to select the best combination of signature computation and sampling technique. The new algorithms are also very fast with execution times an order of magnitude smaller than existing techniques. While some of the algorithms are presented using examples for the purpose of easy readability, these algorithms are very general and can be easily applied to broad range of cases.

    摘要: The present invention relates to a device and method for driving an under damped voice coil motor (VCM) actuator of a camera lens. In one embodiment, the device for driving an under damped VCM actuator comprises a first generator operable to read a first manufacture data from an image signal processor (ISP) and to generate a half natural period, ½ Td, of the VCM actuator by selecting a value approximate to the first data in a first table of the device, a second generator operable to read a second manufacture data from the ISP and to generate the maximum overshoot, K, of the VCM actuator by selecting a value approximate to the second data in a second table of the device, an input shaping signal generator operable to read an input signal corresponding to a desired camera lens moving distance from the ISP and to generate a shaping signal according to the value of the half natural period and the maximum overshoot. The input shaping signal may be produced from second order, third order and fourth order input shaping function. The present invention also provides a simple implementation of a driver configuration to achieve a fast camera lens focus speed, yet robust to tolerate actual system deviation from a manufacture design.
