A product can have multiple functions, and as the technology advances, the function of the product is constantly improved and increased, and video clips are set for each individual function or related functions that are closely related, which is convenient for the user to quickly grasp. One or more features of the product.

In S120, the entry identifier image is compared with the association table to obtain a target preset entry identifier image that matches the entry identifier image, and the association table is a preset entry identifier image and view. The associated table of frequency segments.

A preset table of preset entry identification images and video clips is pre-made. The preset entry identifier image corresponding to the entry identifier image in the product use description can be saved in the association table. For example, when viewing the product usage instructions, the user can scan the first picture in the instruction manual corresponding to the function of interest by using the terminal, and pre-save the same picture in the association table as the first picture, after scanning The first picture is compared with the preset entry identification image saved in the association table, and the picture corresponding to the scanned first picture stored in the association table is found.

2 is a flow chart of a method for using a dynamic presentation provided by this embodiment. This embodiment is described above Based on the technical solution, the implementation of the entry identification image as a picture is provided. Referring to FIG. 2, the method of the dynamic demonstration use description may include S201-S205.

In S201, an entry picture in the usage description is obtained.

Taking the description of the function corresponding to one function of the terminal as an example, the first picture in the instruction description is used as the entry picture. There are many functions of the terminal, and as the technology advances, the function of the terminal is also continuously improved and increased, and the video segment entry picture is set for each individual function or a relatively related function, which is beneficial for the user to watch. Interested in features.

In S202, pixel data of the preset entry picture in the entry picture and the association table are respectively acquired, and corresponding histogram data is respectively calculated according to the entry picture pixel data and the preset entry picture pixel data.

Pre-create an association table of preset entry pictures and video clips. The association table can save all preset entry pictures corresponding to the entry pictures in the terminal usage instructions.

A picture consists of multiple pixels, and the position of each pixel can be represented by coordinates. In this embodiment, the position coordinates of the pixel points of the preset entry picture and the entry picture are determined, and the pixel data corresponding to the entry picture and the preset entry picture corresponding to each position coordinate is calculated.

The histogram includes a gray histogram and an RGB histogram. For grayscale images, you can choose to use the gray histogram for calculation. Since the gray histogram calculation is relatively simple, initialize a histogram array H of size 256. The frequency distribution statistics are completed according to the pixel values, and if the pixel value is 124, then H[124]+=1. For color RGB images, gray histograms or RGB histograms can be used, where RGB histograms are more accurate than gray histograms. The RGB histogram can have a single RGB histogram and a three-dimensional RGB histogram. The three-dimensional RGB histogram is simple and clear compared to a single RGB histogram. For three colors of RGB, three histograms HR, HG, and HB can be defined separately. . Suppose the RGB value of a pixel point P is (4, 231, 129), and the corresponding histogram is calculated as HR[4]+=1, HG[231]+=1, HB[129]+=1, for each Pixels complete statistics to get RGB color histogram data. The single histogram SH of RGB pixels is relatively complicated, and each color has a value range of 0-255. It can be divided into a certain number of aliquots, for example, when divided into 8 equal parts, the range of values per aliquot. It is 32; when divided into 16 equal parts, the range of each aliquot is 16; when divided into 4 equal parts, the range of each aliquot is 64. Suppose the RGB value is (14,68, 221), after dividing into 16 equal parts, the corresponding histogram index value index is: (0, 4, 13), according to the formula of calculating the index value: index=R+G*16+B*16*16, the corresponding correspondence is calculated. The histogram index=0+4*16+13*16*16, and the histogram data is SH[3392]+=1. The RGB pixel values are traversed in this way, and the histogram data calculation is completed.

The calculation method of the histogram data listed here is merely an example and is not intended to limit the technical solution.

In S203, a Pap's coefficient is calculated according to the entrance picture histogram data and the preset entry picture histogram data.

The formula for calculating the Babbitt coefficient is:

Where ρ(p,p') is the Barthel's coefficient, p(i) is the entrance picture histogram data, p'(i) is the preset entrance picture histogram data, and i is the entry picture and the preset entry picture corresponding to The position coordinate of the pixel, where n is the number of position coordinates of the total pixel of the picture.

The Barthel's coefficient can represent the picture similarity value (Pap's coefficient factor value), and the Barth's coefficient range is [0, 1]. The more similar the picture, the higher the similarity. That is, the value of the Barthel's coefficient factor is closer to 1.

In S204, when the Barthel coefficient is greater than a preset Barthel's coefficient threshold, it is determined that the preset entry picture corresponding to the Barthel coefficient is the target preset entry picture.

The value of the Barthel's coefficient threshold is in the range of [0, 1]. When the number of preset entry pictures in the association table is large, the value of the Barthel's coefficient threshold is large, which can improve the accuracy of image matching. When the number of preset entry pictures in the association table is small, the value of the Barthel's coefficient threshold is small. Optionally, the Barthel's coefficient threshold is 0.6. In practice, the Barthel's coefficient threshold can be flexibly selected according to the number of preset entry pictures in the association table. For example, when the number of preset entry pictures in the association table is greater than or equal to 30, the number of preset entry pictures in the association table is determined to be large. To improve the accuracy of picture matching, the Barthel coefficient threshold may be set to be greater than Or equal to 0.9. When the number of preset entry pictures in the association table is less than 30, it is determined that the number of preset entry pictures in the association table is small, and the Barthel coefficient threshold may be set to about 0.6.

In S205, the target video segment associated with the target preset entry picture is retrieved, and the The target video segment is sent to the terminal.

Optionally, the play address of the target video segment associated with the target preset entry image is found by preset an association table of the entry picture and the video segment. Finding the target video segment according to the play address, and sending the target video segment to the terminal for playing.

In the entry picture list in S202, the address of the corresponding video segment is associated with each preset entry picture, and the target preset entry picture corresponding to the entry picture scanned by the terminal is found, and the corresponding target can be obtained by looking up the table. The address of the video clip.

The dynamic presentation instruction method provided in this embodiment obtains the histogram data of the preset entry picture in the entry picture and the association table by acquiring the entry picture in the use description of the terminal camera scan, and calculates the Pap's coefficient according to the histogram data. The target preset entry picture corresponding to the entry picture is matched according to the Barthel coefficient, the target video segment is obtained according to the target preset entry picture, the target video segment is sent to the terminal, and the picture is used as the entry identifier, so that the terminal use description is more beautiful.
