The invention provides an image processing device and an image processing method. The image processing device comprises at least one image capturing device and a processor. The processor receives the first image and the second image from the image capturing device and identifies an overlapping region between the first image and the second image. The processor analyzes the overlapping region to obtain a plurality of feature points, a first optical flow adjustment region and a second optical flow adjustment region, dividing the first optical flow adjustment area and the second optical flow adjustment area into a plurality of triangular blocks by using the feature points as vertexes, the corresponding triangular blocks in the first and second optical flow adjusted regions are mixed to form a stitched region, and the stitched region and a plurality of non-overlapping regions in the first and second images are combined to generate a stitched image. Therefore, the operation complexity is greatly reduced, the better image quality can be achieved, and the method is suitable for various real-time applications such as real-time operation of image splicing, three-dimensional image and image generation.

The invention discloses an image size adjustment method and device and a computer storage medium, and belongs to the technical field of image processing. The method comprises the following steps of: when a sliced image updating operation is detected in a target folder, obtaining size information of a target sliced image corresponding to the sliced image updating operation, wherein the target folder is used for storing sliced images, and the size information indicates pixel counts of a height and a width of the target sliced image; judging whether the target sliced image is in an even number size or not according to the size information; and if the target sliced image is not in the even number size, adjusting the target sliced image to the even number size. If the target sliced image is not in the even number size, the target sliced image is adjusted to the even number size, so that the size adjustment of mass images can be completed without artificially, manually and tediously repeating same operations, thereby saving a lot of time and manpower, reducing the cost and enabling the intelligence to be relatively good.

This image processing device (10) comprises a detecting unit (11) and a specifying unit (12). The detecting unit (11) included in the image processing device (10) detects a region in which pixel values change between frames included in moving picture data. The detecting unit (11) outputs the detection result to the specifying unit (12). The specifying unit (12) sets a rectangle circumscribing the region detected by the detecting unit (11). The specifying unit (12) specifies a frame including an object to be detected on the basis of the occupancy rate of the region with respect to the circumscribing rectangle.

The invention discloses a historical video real-time linear tracking method, which relates to the field of video image processing, and comprises the following steps of: 1, carrying out initializing and loading a library; step 2, carrying out linear tracking processing on historical videos; 3, releasing resources and unloading a library; step 4, ending. In the step 2, human factors are introduced,single-frame rapid playing is carried out on the video according to needs, target object extraction is carried out, a corresponding mark is marked at the position where the target appears, and when the target turns or suddenly changes, tracking is carried out through moving the target mark at the turning point again. Through the implementation of the invention, the precision of the target trackingalgorithm in a complex scene is improved, the problem of target tracking errors or target tracking missing in a complex picture can be solved, the method is not influenced by error timestamp information, and the method is simple and easy to popularize and apply.
