Light stripe projection (LSP) is one of the most robust 3D recognition methods, and the general method of light stripe feature (LSF) detection is Laplacian of Gaussian (LOG) filtering. If distances to objects are various, as in the case of indoor navigation, LSF width becomes various according to distance. As the window size of spatial filtering influences the performance significantly, various...

Studies have shown that patients with schizophrenia exhibit visual processing impairments, particularly regarding the processing of spatial frequencies. In a previous work, we found that, compared to healthy volunteers, patients were biased toward low spatial frequencies (LSF) to identify facial expression at a glance. Given the ubiquity of faces in visual perception, it remains an open questio...

Colorectal cancer (CRC) is the third most common cancer worldwide and the fourth most common cause of cancer death. Therapy failure was the first cause of death. LSF is a transcription factor regulating gene expression of angiogenesis, tumor invasion and proliferation, and is identified as a chemoresistant gene. Real-time PCR and Western blot to analyze mRNA and protein expression of LSF in 23 ...

Discuss challenges in designing post-surgical lumbar spine rehab program for home health patients. Describe common post-surgical lumbar spine fusion (LSF) functional precautions and activities prescribed by the surgeon. Identify the most common approaches to the LSF procedures and main types of lumbar fusions. Identify surgical LSF risk factors related to increased risk of non-union of the fusi...

The Lebesgue spectrum filter (LSF), a finite impulse response (FIR) filter whose coefficients decay exponentially with a negative factor r := √3 − 2, is shown to be effective preprocessing for spreading code in asynchronous code-division multiple-access (CDMA) systems. The LSF has only been studied independently from the well-known minimum mean-square error (MMSE) filter, an optimal FIR filter ...

The transcription factor LSF (Late SV40 Factor), also known as TFCP2, belongs to the LSF/CP2 family related to Grainyhead family of proteins and is involved in many biological events, including regulation of cellular and viral promoters, cell cycle, DNA synthesis, cell survival and Alzheimer's disease. Our recent studies establish an oncogenic role of LSF in Hepatocellular carcinoma (HCC). LSF ...

We developed a bandwidth scalable LSF (Line Spectral Frequency) quantizer utilizing interframe and intraframe prediction. The predictor used in the quantizer was designed as combination of first order AR (auto regressive) prediction and a codebook mapping technique, which maps a narrow band LSF codebook to a wide band LSF codebook. An upsampling process in the autocorrelation domain was utilize...

In four experiments, we investigated how attention to local and global levels of hierarchical Navon figures affected the selection of diagnostic spatial scale information used in scene categorization. We explored this issue by asking observers to classify hybrid images (i.e., images that contain low spatial frequency (LSF) content of one image, and high spatial frequency (HSF) content from a se...

In this paper, we present an optimized trellis coded vector quantization (TCVQ) coding system designed for the effective and robust coding of LSF spectral parameters at low bit rate. The aim of this system, called at the beginning « LSF-OTCVQ Encoder », is to achieve a low bit rate transparent quantization of LSF parameters of the US Federal Standard (FS1016) speech Codage conjoint source-canal...
