20130251207 | Method and System to Detect the Microcalcifications in X-Ray Images Using Nonlinear Energy Operator - A method and system to detect the microcalcifications (MC) in different type of images viz. X-ray images/mammograms/computer tomography with varied densities using nonlinear energy operator (NEO) is disclosed to favor precise detection of early breast cancer. Such Microcalcifications are associated with both high intensity and high frequency content. The same NEO output is useful to detect and remove the irrelevant curvilinear structures (CLS) thereby helps in reducing the false alarms in micro calcification detection technique. This is effective on different dataset (scanned film, mammograms with large spatial resolution such as CR and DR) of varied breast composition (viz. dense, fatty glandular, fatty), demonstrated quantitatively by Free-response receiver operating characteristic (FROC). Importantly, the method and apparatus of the invention can be used in conjunction with machine learning techniques viz. SVM to favor detection of incipient or small microcalcifications, thus benefiting radiologists in confirming detection of micro-calcifications in X-rays images/mammograms and reducing death rates. | 09-26-2013 |
20130243296 | ULTRASOUND IMAGING METHOD/TECHNIQUE FOR SPECKLE REDUCTION/SUPPRESSION IN AN IMPROVED ULTRA SOUND IMAGING SYSTEM - The present invention relates to an improved ultrasound imaging method/technique for speckle reduction/suppression in an ultra sound imaging system in which scan conversion and speckle reduction is performed simultaneously in the scan conversion stage avoiding any kind of conventional interpolation. An improved method for speckle reduction in an ultrasound imaging system and an improved ultra sound imaging system for speckle reduction is provided in the present invention. The method comprises steps of receiving in a processor means raw data samples as an input comprising image signals with noises from a logarithmic amplifier, processing the received image signals for scan conversion and speckle reduction in the processor means so as to get pixel value from the raw data samples and to perform speckle reduction so as to provide speckle filtered output image. | 09-19-2013 |
20130242188 | Method and Apparatus for Detection and Removal of Rain from Videos using Temporal and Spatiotemporal Properties - The invention relates to a new method and system for detection and removal of rain from video using temporal/spatiotemporal properties. Advantageously, the temporal/spatiotemporal properties are involved to separate the rain pixels from the non-rain pixels. It is thus possible by way of the present invention to involve less number of consecutive frames, reducing the buffer size and delay. It works only on the intensity plane which reduces the complexity and execution time significantly along with accurate rain detection. This new technique does not assume the shape, size and velocity of the raindrops which makes it robust to different rain conditions. This method reduces the buffer size which reduces the system cost, delay and power consumption while maintaining sufficient quality of rain detection. | 09-19-2013 |
20120290168 | STATE ESTIMATION, DIAGNOSIS AND CONTROL USING EQUIVALENT TIME SAMPLING - A method and system for using Equivalent Time Sampling to improve the effective sampling rate of sensor data, and using the improved-resolution data for diagnosis and control. Data samples from existing sensors are provided, where the sampling rate of the existing sensors is not sufficient to accurately characterize the parameters being measured. High-resolution data sets are reconstructed using Equivalent Time Sampling. High-resolution input data sets are used in a system model to simulate the performance of the system being measured. Results from the system model, and high-resolution output data sets from Equivalent Time Sampling, are provided to an estimator, which provides accurate estimation of measured quantities and estimation of quantities not measured. Output from the estimator is used for fault diagnosis and control of the system being measured. | 11-15-2012 |
