Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention. Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the invention.
The embodiment of the invention provides a method and a device for realizing image blurring dynamic effect, electronic equipment and a storage medium.
First, a method for implementing an image blur effect according to an embodiment of the present invention is described below.
Fig. 1 is a flowchart of an image blur effect implementation method according to an embodiment of the present invention, where the method is used to implement a blur effect from blur to clear, and the method may be executed by an electronic device, and in practical applications, the electronic device may be a mobile terminal such as a smart phone, a tablet computer, a personal digital assistant, and the like, or a computer device such as a computer, a desktop computer, and as shown in fig. 1, the method may include the following steps: step 101, step 102 and step 103, wherein,
in step 101, original image a is acquired 0 。
In the embodiment of the invention, the original image is an original image for realizing the fuzzy dynamic effect, and in practical application, the original image can be acquired locally from the electronic equipment or can be acquired from other electronic equipment.
In step 102, based on A 0 Generating N blurred images with increasing blur radius { A 1 ,…,A N N is more than or equal to 1 and is an integer.
In the embodiment of the invention, the fuzzy radius is a parameter involved in the image fuzzy processing process, and the larger the fuzzy radius is, the higher the fuzzy degree of the processed fuzzy image is.
In the examples of the present invention, A N Blur radius > A N-1 Blur radius > A N-2 Fuzzy radius of > … > A 1 The blur radius of (i.e. A) N Degree of blurring > A N-1 Degree of blur > A N-2 Degree of blur > … > A 1 Degree of blur.
In the embodiment of the invention, in the process of generating the N blurred images, the N different blur radiuses can be determined firstly, and the blurred image corresponding to each blur radius is generated according to the N blur radiuses. The N fuzzy radii can be set manually, and can be obtained by training a large number of fuzzy dynamic effect samples, and in practical application, the adopted training algorithm can be a neural network algorithm, a logistic regression algorithm, or other algorithms for machine learning.
In the embodiment of the present invention, the blur effect may be a gaussian blur effect, and the blur effect of each image frame in the gaussian blur effect is a gaussian blur effect.
In the embodiment of the invention, a gaussian fuzzy algorithm can be adopted to perform fuzzy processing on the original image for N times, and different fuzzy radiuses are adopted each time the original image is subjected to fuzzy processing, so that N fuzzy images with different fuzzy radiuses, namely N fuzzy images with different fuzzy degrees, are obtained.
Considering that the processing efficiency of the gaussian blurring algorithm is reduced due to the increase of the image size when the image is processed by the gaussian blurring algorithm, the algorithm has too many addition and multiplication operations, resulting in an image with a slightly larger size, and the processing time is several seconds or even tens of seconds, and at this time, if 24 blurred images with different blurring degrees are prepared for 1 second of blurring effect, the time consumption reaches the processing time of the order of minutes.
In view of the above situation, in an embodiment provided by the present invention, considering that the principle of the mean value blurring algorithm is similar to that of the gaussian blurring algorithm, and due to the reusability of the result of the mean value blurring processing, the time consumption for processing the picture can be reduced from the second level to the millisecond level by using the mean value blurring algorithm, and since the image processing effect (i.e., the image blurring effect) of the 3-time mean value blurring algorithm is very close to that of the gaussian blurring algorithm, the step 102 may specifically include the following steps:
pair A by 3 mean fuzzy algorithm 0 Performing blurring processing for N times to obtain N blurred images { A with gradually increased blur radii 1 ,…,A N }。
Therefore, in the embodiment of the invention, the original image can be subjected to fuzzy processing through the 3-time mean value fuzzy algorithm to obtain the fuzzy image for realizing the fuzzy dynamic effect, and the time consumption of the whole fuzzy dynamic effect can be reduced because the 3-time mean value fuzzy algorithm has higher processing speed on the image.
In another embodiment of the present invention, the following algorithm is used to analyze the following data: the image processing speed is inversely proportional to the size of the blur radius in the gaussian blur algorithm, and the image blur effect of the multiple times of the blurred image with the small radius is the same as that of the blurred image with the large radius of the original image, and according to the characteristic, the blur processing can be performed on the basis of the blurred image, at this time, the step 102 may specifically include the following steps:
to A 0 Carrying out small-radius fuzzy processing to obtain a fuzzy image A 1 ；
To A 1 Performing an overlapReplacing fuzzy processing to obtain N-1 fuzzy images A with gradually increased fuzzy radius 2 ,…,A N 。
In the embodiment of the present invention, when generating a plurality of blurred images based on the original image, a small-radius blurred image (that is, a blurred image with a small blur radius) may be generated first, and the small-radius blurred image may be blurred step by step to obtain a large-radius blurred image.
In one example, a is a pair of Gaussian blur algorithms 0 When the blur processing is performed, the blur radius is set to 30, and a is set to 0 Carrying out fuzzy processing to obtain a fuzzy image A with a small radius 1 (ii) a Thereafter, the blur radius was set to 40, and the blurred image a was subjected to 1 Carrying out fuzzy processing to obtain a fuzzy image A 2 By analogy, A is obtained N 。
Therefore, in the embodiment of the invention, the smaller the fuzzy radius of the Gaussian blur algorithm is, the faster the image processing speed is, so that the image processing speed can be increased by performing iterative blur processing based on the original image, and the time consumption of the whole blur effect is further reduced.
In step 103, in the order of the image with a large blur radius above the image with a small blur radius, pair a 0 ,A 1 ,…,A N Performing overlapping arrangement, sequentially arranging A according to the arrangement order N ,…,A 1 The transparency of (2) is adjusted from 0 to 100% to form a blurring effect.
In the embodiment of the invention, the blurred images with slightly different blur radiuses are considered, the visual effect is slightly different, the blur change effect can replace the supplementary frame by using a mode of changing the transparency of the image, and the animation effect is intuitively superior to the simple change of the blur radiuses of the images, so that the images A can be arranged above the images with small blur radiuses according to the arrangement sequence that the images with large blur radiuses are arranged above the images with small blur radiuses 0 ,A 1 ,…,A N Performing overlapping arrangement, sequentially arranging A N ,…,A 1 The transparency of (2) is adjusted from 0 to 100% to form a blurring effect. Because the number of the blurred images adopted by the blurring motion effect is reduced, the number of the processed pictures can be reduced, and the time consumption of the whole blurring motion effect is further reduced.
In an embodiment provided by the present invention, as shown in fig. 2, the step 103 may specifically include the following steps: step 201 and step 202, wherein,
in step 201, A is added N-1 Is arranged in an overlapping manner at A N Below, and A N The transparency of (2) is adjusted from 0 to 100%.
In step 202, when A is to be N When the transparency of (2) is adjusted to 100%, A is determined N-1 Whether or not it is A 0 If so, stopping adjusting the transparency of the image, otherwise, continuously overlapping the set image and the adjusted transparency of the image until A is equal to A 0 Is arranged in an overlapping manner at A 1 And A is 1 The transparency of (2) is adjusted from 0 to 100%, and the adjustment of the transparency of the image is stopped.
For ease of understanding, a will be described first with reference to a specific example N-1 Is arranged in an overlapping manner at A N Below, raise A N To full transparency when A N-1 Fully exhibiting, then A N-2 Is arranged in an overlapping manner at A N-1 Below, and raise A N-1 By analogy, the transparency of (1) is continued until A 0 The display is complete.
In a more specific example, N is 3 and the original image is A 0 The 3 blurred images with gradually increased blur radius are respectively: a. the 1 、A 2 And A 3 . Firstly, A is firstly 2 Is arranged in an overlapping manner at A 3 Below, A is 3 The transparency of (A) is gradually adjusted from 0 to 100%, in which case A 2 Fully displaying; continue to A 1 Is arranged in an overlapping manner at A 2 And A is 2 The transparency of (A) is gradually adjusted from 0 to 100% when A 1 Fully displaying; continue to combine A 0 Is arranged in an overlapping manner at A 1 And A is 1 The transparency of (A) is gradually adjusted from 0 to 100%, in which case A 0 Complete demonstration, implementation A 0 The dynamic display process from fuzzy to clear.
Therefore, in the embodiment of the invention, two images in the images for realizing the blur dynamic effect can be sequentially overlapped, and the blur dynamic effect is formed by gradually adjusting the transparency of the upper image.
In another embodiment provided by the present invention, as shown in fig. 3, the step 103 may specifically include the following steps: step 301 and step 302, wherein,
in step 301, in the order of the image with a large blur radius being located above the image with a small blur radius, a 0 ,A 1 ,…,A N Overlapping to form N +1 layers, wherein the top layer of the N +1 layers is A N The bottom layer is A 0 And the initial transparency of the N +1 image layers is 0.
In step 302, starting from the top layer, the transparency of the top layer is adjusted from 0 to 100%, when the transparency of the top layer is adjusted to 100%, it is determined whether the next layer is the bottom layer, if so, the transparency of the next layer is stopped to be adjusted, otherwise, the transparency of the next layer is continuously adjusted until the transparency of the previous layer of the bottom layer is adjusted from 0 to 100%, and the transparency of the layer is stopped to be adjusted.
For ease of understanding, a will be described first with reference to a specific example 0 、A 1 ,…,A N Performing overlapping arrangement, specifically, arranging A N Arranged on the uppermost layer (i.e. top layer) and A N-1 Is arranged at the next layer, A N-2 Is arranged on the next layer, and so on, A 0 And the image layers are arranged on the last layer (namely the bottom layer) to form N +1 image layers. Then, starting from the uppermost layer, A is added N The transparency of (A) is gradually adjusted from 0 to 100%, in which case A N-1 Fully displaying; continue to combine A N-1 The transparency of (A) is gradually adjusted from 0 to 100%, in which case A N-2 Show completely, analogize until A 0 The display is complete.
In a more specific example, N is 3 and the original image is A 0 The 3 blurred images with gradually increased blur radius are respectively: a. the 1 、A 2 And A 3 . Firstly, A is firstly 0 、A 1 、A 2 And A 3 Performing overlapping arrangement, specifically, arranging A 3 Arranged at the uppermost layer (i.e. the top layer), A 2 Is arranged at the nextLayer of A 1 Is arranged at the next layer, A 0 And is arranged on the last layer (namely, the bottom layer) to form 4 layers. Then, starting from the uppermost layer, A is added 3 The transparency of (A) is gradually adjusted from 0 to 100%, in which case A 2 Fully displaying; continue to combine A 2 The transparency of (A) is gradually adjusted from 0 to 100%, in which case A 1 Fully displaying; continue to combine A 1 The transparency of (A) is gradually adjusted from 0 to 100%, in which case A 0 Complete demonstration, implementation A 0 The dynamic display process from fuzzy to clear.
Therefore, in the embodiment of the invention, all the images for realizing the fuzzy dynamic effect can be integrally overlapped, and the transparency of each fuzzy image is sequentially adjusted according to the sequence from top to bottom to form the fuzzy dynamic effect.
In the embodiment of the invention, the blurring effect is formed by a frame supplementing mode of transparency change, if the blurring effect is 1 second, only 1-4 blurring images are needed, and correspondingly, the value of N in the step 102 is 1-4.
In the embodiment of the invention, when the transparency of the blurred image is adjusted, the adjustment can be performed according to a certain rate, wherein the rate can be set manually or obtained by training a large number of blurred dynamic effect samples, and in practical application, the adopted training algorithm can be a neural network algorithm, a logistic regression algorithm and the like, and can also be other algorithms for machine learning.
As can be seen from the above embodiments, in this embodiment, the blurred image and the original image are overlapped, the transparency of each blurred image is sequentially adjusted, and the blur effect is formed by changing the transparency to complement the frame. Compared with the prior art, the method and the device have the advantages that the fuzzy dynamic effect can be realized only by a small amount of fuzzy images, the image processing quantity is reduced, and the time consumption of the whole process is short.
The fuzzy dynamic effect scheme from fuzzy to clear is provided in the above embodiments, and the fuzzy dynamic effect scheme from clear to fuzzy is also provided based on the same idea as the fuzzy dynamic effect.

in step 401, original image B is acquired 0 。
In step 402, based on B 0 Generating M blurred images with increasing blur radius { B 1 ,…,B M M is an integer greater than or equal to 1.

In the examples of the present invention, B M Blur radius > B M-1 Blur radius > B M-2 Fuzzy radius > … > B 1 Radius of blur, i.e. B M Degree of blur > B M-1 Degree of blurring > B M-2 Degree of blur > … > B 1 Degree of blur.
In step 403, in the order of setting the image with small blur radius above the image with large blur radius, pair B 0 ,B 1 ,…,B M Performing overlapping arrangement, sequentially arranging B according to the arrangement order 0 ,B 1 ,…,B M-1 The transparency of (2) is adjusted from 0 to 100% to form a blurring effect.
