Embodiment Construction

[0220] An image pyramid is a collection of images of progressively lower resolution arranged in a pyramid shape. For example, figure 1 It shows the image set composed of the 3-level image pyramid of image I. The left picture is the image of the image pyramid level 0 of the image I, the middle picture is the image of the image pyramid level 1 of the image I, and the right picture is the image of the image I Image of pyramid level 2. Types of image pyramids may include primitive pyramids, gradient pyramids, and the like. The original pyramid refers to the image pyramid represented by the original features of the image, such as gray value and / or color value, and the gradient pyramid refers to the image pyramid represented by the gradient feature of the original pyramid.

[0221] Using image pyramids for data processing is widely used in visual tracking and other fields. The KLT (Kanade-Lucas-Tomasi) algorithm is taken as an example below to illustrate.

Abstract

The invention provides a data processing method, a device and a system thereof. The data processing method comprises the steps of reading to-be-processed data of the current layer of one or a plurality of image pyramids from a first storage unit and transmitting the data to a second storage unit; calculating the processing result of the current layer according to the to-be-processed data of the current layer stored in the second storage unit; and in calculating the processing result of the current layer, reading the to-be-processed data of the next layer of the image pyramid from the first storage unit. According to the data processing method, when the image pyramid is used for performing data processing, processing result calculation finishing of the current layer is not required, and the to-be-processed data of the next layer is read in calculating the processing result of the current layer, thereby realizing calculation to the next layer. Therefore the data processing method, the device and the system thereof have advantages of realizing data processing process optimization, reducing waiting time in an reading operation, reducing time consumption and improving real-time performance.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular, to a data processing method, device, and system. Background technique [0002] With the development of computer technology, the use of image pyramids for data processing has been widely used in many technical fields, especially in the field of visual tracking. [0003] At present, when using the image pyramid for data processing, the data processing process is usually: the reading module reads the data to be processed in the first layer of the image pyramid from the external memory, and the calculation module calculates the processing result of the layer according to the data to be processed in the layer, The reading module and computing module repeat the above process until the entire data processing process is completed. [0004] However, the above data processing process usually takes a long time, resulting in poor real-time performance. Cont...
