Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Fig. 1 is the synoptic diagram according to the key step of the deep or light method of the adjustment space of a whole page of the embodiment of the invention, and as shown in Figure 1, this method mainly comprises the steps:
Step S11: the position of determining the character in the space of a whole page;
Step S13: the deep or light degree of calculating each character in the space of a whole page;
Step S15: the whole deep or light degree of character of determining the space of a whole page according to the deep or light degree of each character;
Step S17: the space of a whole page is carried out deep or light adjusting based on the whole deep or light degree of the character of the space of a whole page.
From above-mentioned steps as can be seen, carry out deep or light adjustment at the character on the space of a whole page in the present embodiment, determine character position and deep or light degree thereof, adjust the deep or light of the space of a whole page then on the whole, this mode has been avoided the influence of the local deep or light value in the space of a whole page for character, make the deep or light of character meet default requirement, thereby help to improve the effect of the deep or light adjustment of the space of a whole page.
Before step S13, can with the adjusted size of the character in the space of a whole page unified value.Helping like this has unified standard to the deep or light degree of character.Can adopt algorithm in advance during calculating in carrying out step S13, the algorithm of preliminary election can be the black-white point ratio of the pixel in the calculating character; In the adjusted size with the character in the space of a whole page is under the situation of unified value, and the algorithm of preliminary election also can be the black-white point ratio of the pixel in the unit length lines of calculating character.
In step S15, specifically can be the deep or light degree mean value that calculates the character in the space of a whole page according to the deep or light degree of each character in the space of a whole page, with the deep or light degree of character integral body of this mean value as the space of a whole page.
Carry out OCR if desired after the deep or light adjusting among the step S17, Ci Shi deep or light adjusting can be selected concrete control method at the OCR algorithm that will use so, helps to obtain preferable OCR result like this.
