Embodiment 1

[0045] Such as figure 1 As shown, a method of quickly searching for questions through pictures includes:

[0046] S101. Obtain a compressed title picture.

[0047] In this embodiment, what the server obtains is the compressed title picture, and since the size of the compressed picture is small, the transmission speed is very fast.

[0048] S102. Extract fingerprint feature values ​​of the compressed title picture.

[0049] In this embodiment, the fingerprint feature value of the compressed picture is extracted and converted into a series of numbers to form a special picture fingerprint, which makes the occupied memory smaller and improves the running speed.

[0050] S103. Match the fingerprint feature value with the fingerprint feature value of the title picture in the gallery, and obtain the target picture from the gallery.

[0051] Specifically, the fingerprint feature value corresponding to the topic picture will be pre-stored in the gallery, and the fingerprint feature ...

Embodiment 2

[0055] Such as figure 2 As shown, a method of quickly searching for questions through pictures includes:

[0056] S201. Obtain a compressed title picture.

[0057] Specifically, each question picture is compressed into an 8*8-pixel question picture, and each compressed question picture has a total of 64 pixels.

[0058] S202. Extract the fingerprint feature value of the compressed title image.

[0059] Specifically, the extracting the fingerprint feature value of the compressed title picture includes: calculating the average gray value of the 64 pixels, and comparing the gray value of each pixel with the average gray value in turn, If the gray value of the pixel is greater than or equal to the average gray value, the pixel is marked as 1, and if the pixel is smaller than the average gray value, the pixel is marked as 0, and a 64-bit binary code is obtained.

[0060] As another implementation manner of the present invention, after obtaining the 64-bit binary code, the metho...

Embodiment 3

[0071] This embodiment provides a method for quickly searching for questions through pictures, which is specifically implemented through workflows in the client and server.

[0072] Such as image 3 As shown, a method of quickly searching for questions through pictures includes:

[0073] S301. The client acquires a title picture; compresses the title picture; and uploads the compressed title picture.

[0074] In this embodiment, the client takes pictures with a camera to obtain a title picture, and then automatically crops, grayscale converts, and compresses the title picture and uploads it to the server. The size of the compressed image is very small, so it takes up very little space, and the uploading process is faster, which reduces the waiting time of the user.

[0075] S302. The server obtains the compressed title picture; extracts the fingerprint feature value of the compressed title picture; matches the fingerprint feature value with the fingerprint feature value of t...

Abstract

The invention discloses a method and a system for quickly searching for a title through a picture. The method comprises: obtaining a compressed title picture; extracting a fingerprint eigenvalue of the compressed title picture; matching the fingerprint eigenvalue with fingerprint eigenvalues of title pictures in a picture library, and obtaining a target picture from the picture library; and pushing a title corresponding to the target picture. According to the method and the system, the compressed picture is uploaded to a server, so that the waiting time of a user is shortened in a transmission process of the compressed picture; and then picture features are extracted through a fingerprint algorithm and matched with the picture eigenvalues in the picture library, and the picture features are numbers, so that the matching time in a title search process is shortened.

Description

technical field [0001] The present invention relates to the field of searching questions by pictures, in particular to a method and system for quickly searching questions by using pictures. Background technique [0002] Most of the current search tool apps rely on taking pictures and keyboard input to search questions. Taking pictures and searching questions can greatly reduce the input cost of users, but the current mainstream method is to recognize the text in the picture through OCR, and then extract the recognized text. Text keywords to search, so as to match the best search results. In this process, if the question stem information is too long or the question stem information is too large, it will take a long time to identify, which will increase the waiting time of the user in the search question process and affect the user experience. Contents of the invention [0003] The purpose of the present invention is to provide a method and system for quickly searching for ...
