In this paper, we introduce a tone mapping algorithm for processing high-brightness video images. This method can maximally recover the information of areas and preserve detailed information. Along with benchmark data, real-life practical application data were taken to test proposed method. The experimental objects license plates. We reconstructed image in RGB channel, gamma correction was carr...

Retinal lateral inhibition is one of the conventional efficient coding mechanisms in the visual system that is produced by interneurons that pool signals over a neighborhood of presynaptic feedforward cells and send inhibitory signals back to them. Thus, the receptive-field (RF) of a retinal ganglion cell has a center-surround receptive-field (RF) profile that is classically represented as a di...

BACKGROUND The present investigation aimed at assessing the possibility of distinguishing between malignant and benign breast lesions by measuring the signal intensity in vessels of the suspect lesions over time after administration of the ultrasound contrast agent Levovist. MATERIALS AND METHODS Levovist was administered intravenously to 21 patients with breast cancer and 12 patients with a ...

The White effect [Perception 8 (1979) 413] cannot be simply explained as due to either brightness contrast or brightness assimilation because the direction of the induced brightness change does not correlate with the amount of black or white border in contact with the gray test patch. This has led some investigators to abandon spatial filtering explanations not only for the White effect but for...
