Or brightness can be adjusted to suitable value, so that the object on image to be marked be allow to highlight, improve to object
The accuracy of profile mark.
Fig. 3 is the flow diagram of the mask method of image in another embodiment, and the present embodiment is related to a kind of computer
Equipment increases the mode of visual aids layer on image to be marked, on the basis of the above embodiments, as shown in figure 3, above-mentioned
S102 includes:
S201, according to the comparison result of the color value of pixel and preset threshold in image to be marked, determine visual aids layer
Color and/or transparency.
Computer equipment can be determined in the comparison result according to the color value of pixel and preset threshold in image to be marked
The color and/or transparency of visual aids layer, then set identified face for the color of visual aids layer and/or transparency
Color and/or transparency, and by the addition of above-mentioned visual aids layer on image to be marked.
Optionally, if the color value that comparison result is pixel in image to be marked is greater than preset threshold, computer equipment
The color for determining visual aids layer is black；If the color value that comparison result is pixel in image to be marked is not more than default threshold
Value, it is determined that the color of visual aids layer is white.
Specifically, if the color value that comparison result is pixel in image to be marked is greater than preset threshold, then computer is set
It is standby to think that the color of pixel in above-mentioned image to be marked is excessively bright, it can be to be marked to adjust by increasing the visual aids layer of black
The color and/or brightness of image；If the color value that comparison result is pixel in image to be marked is not more than preset threshold, then counting
It calculates machine equipment and thinks that the color of pixel in above-mentioned image to be marked is excessively dark, can be adjusted by increasing the visual aids layer of white
The color and/or brightness of image to be marked.
Further, computer equipment can determine the transparency of above-mentioned visual aids layer, Ke Yigen according to comparison result
According to the judgment threshold area of the color value of pixel and the difference of preset threshold and difference in image to be marked in above-mentioned comparison result
Between, to directly determine the transparency of above-mentioned visual aids layer；Optionally, computer equipment can also be according to above-mentioned comparison result
Size determines the adjusted value of transparency, then according to adjusted value and preset benchmark transparency, determines the transparent of visual aids layer
Degree.Assume that above-mentioned comparison result is M, can according to the size of M, to determine the adjusted value of transparency, for example, if 0≤M <
20, it can determine that above-mentioned adjusted value is 0.1, if 20≤M < 40, can determine that above-mentioned adjusted value is 0.2, if 40≤M < 60
Can determine above-mentioned adjusted value be 0.3 etc., for adjusted value method of determination it is not limited here.
S202, color and/or transparency according to visual aids layer increase visual aids layer on image to be marked, with
Obtain target image.
On the basis of obtaining the color and/or transparency of above-mentioned visual aids layer, computer equipment can be according to upper
Color and/or transparency are stated, increases the visual aids layer of corresponding color and/or transparency, on image to be marked to obtain mesh
Logo image.Assuming that the color value of a pixel M is (A1, A2, A3), the face of each pixel of visual aids layer in image to be marked
Color value is (B1, B2, B3), then computer equipment can be according to formula Ci=Bi×d+Ai× (1-d), wherein d is above-mentioned
The transparency of visual aids layer, come obtain in target image adjusted with the color value of the pixel C of pixel M location matches (C1,
C2, C3).
Continue to obtain in corresponding embodiment according to fig. 2 by taking an image to be marked comprising 420*420 pixel as an example
Comparison result, computer equipment can consider pixel in above-mentioned image to be marked average color be greater than preset threshold, that
The color that can determine visual aids layer is black；Further, according to being above-mentioned comparison result 8, computer equipment can be with
The difference of the average color and preset threshold that think above-mentioned image to be marked is little, and the benchmark transparency of visual aids layer can be with
It is 0, appropriate adjustment is carried out on the basis of said reference transparency, such as can determine according to section 0≤8 < 20 is judged
The adjusted value of above-mentioned transparency is 0.1, then can determine visual aids layer according to above-mentioned adjusted value and said reference transparency
Transparency be 0.1.Such as in above-mentioned image to be marked one of pixel M color value be (140,160,220) when, due to
The color of visual aids layer is that black obtains then the color value of each pixel of visual aids layer is (0,0,0) according to above-mentioned
The transparency d=0.1 of the visual aids layer taken, passes through formula Ci=Bi×d+AiPixel in the available target image of × (1-d)
The color value of N, for (126,144,198)；It can be seen from above-mentioned calculated result by be arranged visual aids layer color be it is black
The color value of color, transparency 0.1, the pixel N in above-mentioned target image is respectively less than the color of pixel M in above-mentioned image to be marked
Value, that is, reduce the brightness of image to be marked.
The mask method of above-mentioned image, computer equipment according to the color and/or transparency of the visual aids layer of acquisition come
Visual aids layer is added, so that the setting of the color and/or transparency of above-mentioned visual aids layer is more suitable, it can be to be marked
