Embodiment
The present invention mainly relates to a kind of image processor and image treatment method thereof.It should be noted that, following examples are in order to illustrate technology contents of the present invention, not in order to limit the scope of the invention.Moreover in following examples and accompanying drawing, element unrelated to the invention has omitted and has not illustrated, and in graphic, each interelement size relationship is only for asking easy understanding, non-in order to limit actual ratio.
As shown in Figure 1, it is the schematic diagram of an image processor 1 to the first embodiment of the present invention.Image processor 1 comprises a processor 11.Image processor 1 can be a camera, a video camera, a smart mobile phone or arbitrary device with image processing ability.
A raw video 102 is divided into multiple groups image 104 by processor 11.Subsequently, each group image is rotated to an angle, to produce an image output 106.Particularly, raw video 102 is images that comprise multiple independent notes, as shown in Figure 2 A.Processor 102 is analyzed raw video 102, to be divided into multiple groups image 104, as shown in Figure 2 B.Finally, each group image 104 is rotated an angle by processor 11, so that it is proper, and produces image output 106(as shown in Figure 2 C), read for a user.
How following declarative description processor 11 is divided into one of these group's images 104 by raw video 102 is implemented aspect.Conventionally nearer based on each notes described content distance to each other, first, raw video 102 is converted to a grayscale image by processor 11, and grayscale image two-value is turned to a binaryzation image.Then, processor 11, based on the one 8 adjacent algorithms (8-neighbor connectivity algorithm) that are communicated with, is multiple parts by binaryzation Image Segmentation.Due to the 8 adjacent known technologies that are communicated with calculation this area owned by France, therefore not in this to go forth.
Subsequently, processor 11, according to the Euclidean distance between each several part (Euclidean distance), is divided into multiple groups by these parts, and according to these groups, produces these group's images 104.In detail, processor 11 is Euclidean distances of calculating between each several part, if the Euclidean distance between some part is less than a preset value, these parts is attributed to same group.
In addition, implement in aspect in another, the processor 11 more record content based on difference notes should use the pen of different colours to write, so that raw video 102 is divided into multiple parts.First, processor 11 is analyzed multiple line colors of raw video 102, and according to these line colors, raw video 102 is divided into multiple parts.Then, according to the Euclidean distance between each several part, these parts are divided into multiple groups, and according to these groups, produce these group's images 104.
In addition, implement in aspect in another, the processor 11 more record content based on difference notes should use the pen of different line weights to write, so that raw video 102 is divided into multiple parts.First, processor 11 is analyzed multiple line weights of raw video 102, and according to these line weights, raw video 102 is divided into multiple parts.Then, according to the Euclidean distance between each several part, these parts are divided into multiple groups, and according to these groups, produce these group's images 104.
How following declarative description processor 11 rotates one of an angle by each group image 104 is implemented aspect.First, each group image 104 is carried out an optics character identification by processor 11, to identify multiple characters, and according to a character presentation direction of these characters of Ge Gai group image, determines the angle of the each group of rotation image 104.In detail, owing to writing common can carrying out by along continuous straight runs, thus after character is identified, can obtain the horizontal direction of notes, to obtain the angle of rotation.
In addition, implement in aspect in another, processor 11 can detect the grid in each group image 104, and according to the grid of each group image 104, determines the angle of the each group of rotation image 104.In detail, if notes system writes in the paper with grid, be upright shape based on grid, therefore can obtain the angle of rotation.
In addition, implement in aspect in another, processor 11 can carry out each group image 104 an optics character identification, to identify multiple characters, and according to one of these characters of each group image 104 lines around, determines the angle of the each group of rotation image 104.In detail, the emphasis mark of word and the mode of mark can be generally to horizontal line owing to writing conventionally, therefore after character is identified, can, according to these characters horizontal line around, obtain the angle of rotation.
As shown in Figure 2, it is the schematic diagram of an image processor 2 to the second embodiment of the present invention.In the present embodiment, image processor 2, except comprising processor 11, more comprises a receiver 13, and it is electrically connected to processor 11.
