Abstract

A method for dividing an image obtains the image by captured and a depth map of the image. The method creates a histogram of the depth map including horizontal and vertical axes. A clustering algorithm is applied to the data in the histogram to determine upon two data clusters and the cluster centers of the two clusters. The method determines that the abscissa value of the smallest ordinate value between two cluster centers in the histogram is a segmentation threshold. If the obtained segmentation threshold meets a preset condition, the image is segmented into a foreground region and a background region. An electronic device for applying the method is also provided.

Abstract

A method for generating dynamic images applied to a computer device includes obtaining a depth image of a static image. A preset region of the depth image is converted into a histogram and an average depth value D is calculated therefrom. A first depth value d1 and a second depth value d2 are determined from the histogram according to the average depth value D. M numbers of third depth values d3 are calculated according to the first depth value d1 and the second depth value d2. Once M number of blurred images are generated according to each M number of third depth values d3, the M number of blurred images are played back according to a magnitude of the third depth value d3 corresponding to each of the M number of blurred images.

Abstract

An antenna structure includes a side frame, a first feed portion, a second feed portion, and a first ground portion. The side frame defines a first gap and a second gap. The side frame is divided into a first radiating portion by the first gap and the second gap. When the first feed portion supplies current, the current flows through a first resonance section and is grounded through the first ground portion to activate a first operating mode and a second operating mode. When the first feed portion supplies current, the current flows through a second resonance section and is grounded through the second feed portion to activate a third operating mode. When the second feed portion supplies current, the current flows through the second resonance section and the first resonance section, and is grounded through the first ground portion to activate a fourth operating mode.

Abstract

An optical projector module to establish distance to target object in a field of view for three dimensional image acquisition purposes includes a printed circuit board, point light sources mounted on the printed circuit board to emit a plurality of light beams, a lens unit apart from the plurality of point light sources, and a distance adjusting unit connected to the lens unit. A memory storage device is also included. The lens unit comprises separated lenses, the adjusting unit can adjust distances between the lenses of the lens unit, and light beams with a number of light spot patterns can accordingly be projected. Previously-captured images in the memory storage device can be referred to in seeking target objects in the field of view and light beams in different spot-concentrations on or around the target object enable calculations for the capture of images in three dimensions of the target object.

Abstract

An antenna structure includes a housing, a feeding portion, and a connecting portion. The housing defines a gap and a groove. The housing forms a radiating portion and a coupling portion through the gap and the groove. A portion of the housing between the feeding portion and the gap forms a first radiating section. The connecting portion is electrically connected to one end of the coupling portion adjacent to the gap. When the feeding portion supplies current, the current flows through the feeding portion and the first radiating section, and is coupled to the connecting portion through the gap to activate a first operating mode. When the feeding portion supplies current, the current flows through the feeding portion and the first radiating section, and is coupled to the coupling portion through the gap to activate a second operating mode.

Abstract

An envelope tracking device includes a fine slot peak tracking (FSPT) circuit, at least one power amplifier, and an envelope modulator. The FSPT circuit is connected to the power amplifier through the envelope modulator. The FSPT circuit generates envelope signals based on input signals, adds an offset to the envelope signals, and expands and smoothes the added envelope signals. The envelope modulator generates envelope voltage signals according to the smoothed envelope signals, and outputs the signals to drain of the power amplifier. The envelope voltage signals are time-aligned with the amplified signals which are transmitted to gate of the power amplifier.
