A canvas element based on the information of the image is created, and a canvas element is drawn based on the information of the image. Attached recognition information is obtained. A block element based on the attached information is created, and the attached information is set into the block element. The canvas element and the block element are composed and stacked on a web page. The canvas element and the block element are displayed in the web page. An electronic device, and a non-transitory computer readable storage medium applying the method are also provided.

## Background
FIELD
The subject matter herein generally relates to image processing, particularly to web video processing, a method for optimizing the image processing of web videos, an electronic device, and a storage medium applying the method.
BACKGROUND
During the manufacturing of integrated circuit (IC) chips, manufacturers need to collect golden samples of the mass-produced IC chips, and label the IC chips which are found to have defects. A camera system films a first video of the non-inspected IC chips. The first video is then imported into a recognition system. The recognition system can process the first video to export the bounding box of the IC chips with attached information of the corresponding position coordinates. The first video and the attached information are transmitted from a server to a client. The first video and the attached information were combined to form a second video before showing to users. The users can collect the golden samples and label the IC chips with the defects based on the second video and the attached information.
During the transmission of the first video and the attached information from the server to the client, the server compresses the first video and the attached information using a variable bitrate (VBR) technology. The image quality of the compressed video is low, and the clarity of the attached information is also lowered accordingly. The attached information can include detail content, such as texts or lines, so this can affect the user recognition of the second video if the attached information is not clear enough after the compression.
The algorithms in the recognition system for analyzing and processing the first video is complex. Since the processing duration may be slower than the time for a frame to be captured, the processing speed of the recognition system and the output frame rate of the camera system are not the same, and the attached information may not be able to synchronized with the first video. For maintaining the frame rate of the camera system, a determining component is required for determining whether the recognition system is able to output the attached information, which is not synchronized with the first video, under the frame rate of the camera system. Thus, the development cost of the system is increased, and the transmission becomes a complex operation.
Thus, there is room for improvement in the art.

As shown in FIG. 1, the method includes the following steps. These steps may be re-ordered:
In block S101, a size of an image is obtained.
In one embodiment, the image is a frame of a video filmed by an external camera system 200 (as shown in FIG. 5). The size of the image includes the width and height of the image. The external camera system 200 is configured to film the target objects which need to be sampled or labeled with defects.
In one embodiment, the external camera system 200 can be one or more cameras, and can also be one or more video capturing devices.
In one embodiment, the size of the image can be obtained from the external camera system 200 through an application programming interface (API). The API can be several pre-defined functions to provide applications or developers with an access to independent services running on external software or hardware, without accessing source codes. For example, the size of the image is obtained form the external camera system 200 through the API.
In block S102, pixel information of the image is obtained.
In one embodiment, the external camera system 200 transmits the pixel information to the electronic device 400 through WebSocket. The WebSocket is a protocol in a full-duplex communication over a single transmission control protocol (TCP). The WebSocket allows a server to proactively push data to clients. A persistent connection between the server and the clients can be established, which allows two-way data transmission. The pixel information of the image is a set of RGB values and a transparency value of each pixel in the image, a format of which is an ArrayBuffer object. The ArrayBuffer object is representation for continuous binary data, storing an array of bytes. Directly reading and writing the contents of the ArrayBuffer object are not allowed, but this can be achieved using a TypedArray object or a DataView object. The TypeArray object is an array of typed data, which provides an array-like view of the underlying binary data buffer for reading or writing data in the ArrayBuffer object. DataView object is a low-level interface for reading or writing values in multiple data types in the ArrayBuffer object.
In one embodiment, the electronic device 400 using the method can include one or more controlling buttons (not shown) with specified names can be defined, and can also include one or more monitoring units (not shown). The specified names can be defined by different functions. The controlling buttons control states of the electronic device 400. The monitor monitoring units the states of the electronic device 400.

The external recognition system 300 processes the image obtained in block S101 attach recognition information. The recognition information includes the size and the coordinates of the bounding box of the recognizing object. The recognition parameters are used for informing the external recognition system 300 about the type and the size of the recognizing object to the external recognition system 300.
In block S107, the attached recognition information of the image is obtained.
In one embodiment, the external recognition system 300 sends the attached recognition information of the image using a Server-Sent Events (SSE). SSE enables the external recognition system 300 to push data, and maintains the connection to the electronic device 400. The external recognition system 300 can keep sending the latest data.
The electronic device 400 receives the attached information through SSE. The attached information is in a JavaScript Object Notation (JSON) format. The JSON format is a data storing format, which is language-agnostic and lightweight. Using the JSON format for transmitting the attached information, a resource utilization of the server and the client can be reduced, and an amount of data stored in the server and the client can be decreased.
In one embodiment, the electronic device 400 using the method can include one or more controlling buttons with specified names, and one or more monitoring units.
