The PMP Growth algorithm described herein provides for image tracking, segmentation and processing in environments where the camera system moves around a great deal, i.e., causing image jumps from one image frame to the next. It also is operative in systems where the objects themselves are making quick movements that alter their path. Attributes of the PMP Growth algorithm allow tracking systems using the PMP Growth algorithm to follow objects a long distance in a scene. This detection and tracking method is designed to track objects within a sequence of video image frames, and includes detecting keypoints in a current image frame of the video image frames, assigning local appearance features to the detected keypoints, establishing Point-Motion-Pairs between two successive image frames of the video image frames, and accumulating additional matches between image locations to form complete coherent motion object models of the objects being tracked. The segmentation aspect permits for the discovery of different coherently moving regions in the images.

The lens of the present invention relates to multifocal spectacle lenses, including bifocal and trifocal lenses, with improved cosmetic appearance, optical performance and wide visual field. The lens comprises a plurality of axially layered and bonded lens sections of continuous curvature at least one of which has a changing refractive index incorporating a refractive index blend area oriented transverse to a meridian of the lens. The blend eliminates visibility of the joining area of adjacent portions of generally constant refractive index and the abrupt magnification shift and image jump typical of segmented multifocal lenses. The areas of generally constant refractive index provide the refractive powers for corresponding discrete vision portions of the lens. The other layer(s) of the lens incorporates a constant or similarly changing refractive index.

A method for managing downloading of images associated with image jumps liable to be implemented during accelerated playback of content. The content is able to be downloaded from a communications network. According to the method at least one image associated with a jump is downloaded in advance.

The invention relates to a multifunctional myopic control eyeglass. The eyeglass which comprises a glass frame with height-adjustable nose supports, and eyeglasses is characterized in that: each eyeglass comprises an upper far luminosity zone, a middle zone and a lower close reading zone; and there is a visual channel with two degree changes, wherein one degree change is between the optical center of the upper far luminosity zone and the optical center of the middle zone just below the upper far luminosity zone, and the other degree change is between the optical center of the middle zone and the optical center of the close reading zone just below the middle zone. The eyeglasses are specially divided into three zones for the zero adjustment and the zero aggregation of reading and writing in the invention, so problems of the adjustment and the aggregation of close range reading and writing are thoroughly solved, the visual fatigue is eliminated, and myopia and degree increase are prevented, thereby present computer times of the comprehensive eye utilization are complied. The multifunctional myopic control eyeglass which allows previous neglected computer groups to be substantially facilitated allows the visual field to be clear, real and stable through the humanized zone height of each zone of the eyeglasses. The three zones which are used for cooperating with the adjustment of the eyeglass frame allow an image jumping phenomenon to be avoided. The wearing position of the eyeglass is accurate to guarantee the correct utilization of each zone, prevent the generation and the development of myopia caused by the fatigue of internal and external muscles of eyes and ciliary muscles.

The invention proposes a decoding method for jumping over a macro block during video encoding, comprises: reading encoding sign of a current image jumping over the macro block from a code stream, judging encoding type of the current image jumping over the macro block based on the encoding sign; selecting a macro block type decoding manner according to the encoding type, decoding the macro block type of the current macro block of the current image by using a run decoding manner or a decoding manner of jumping over the macro block number and combining the macro block type, and decording the macro block self-data for the macro block of the current image; judging whether the current macro block is a last encoded macro block of the current image, if it is, decoding is finished, otherwise, decoding is continuously performed. The invention improves image encoding efficiency, reduces cost for transport and storage by adaptively selecting an encoding manner of the video image jumping over the macro block and a corresponding decoding manner, thereby the invention is an easy and available technic scheme, and can be executed in frame encoding or field encoding.

This application relates to the field of video processing, and discloses a video stitching method, device, electronic equipment, and computer-readable storage medium, wherein the video stitching method includes: detecting the similarity between the first image and the second image, and the first image is the last frame image of the first video to be spliced, and the second image is the first frame image of the second video to be spliced; then, if the similarity satisfies the preset condition, then determine the motion of the first image relative to the second image vector; then, according to the motion vector, determine at least one compensation frame between the first image and the second image, and splice the first image and the second image based on at least one compensation frame, so as to splice the first video to be spliced ​​and the second video The second is to splice the video. The method of the embodiment of the present application can smoothly compensate the jitter occurring at the junction in real time and efficiently, so that the transition between multiple videos can be smooth, and effectively reduce the occurrence of image jitter or image jump after multiple videos are spliced.
