1、Good morning,everybody,my name is xxxx ,today I’m going to talk about my paper,my paper’s topic Automatic image stitching technology bad on SIFT algorithm rearch.
2 、I will introduce my paper from three aspects.they are what,why and how,Firstly what What is image stitching,then why Why do I study image stitching,last how The rearch methods of image stitching.
3、报纸的拼音Let's e what is image stitching Image stitching technology is the number of pieces of overlap image compo a large amless high-resolution(高分辨率) images of technology. Attention,murderthe image which may be different time, different Angle of view(视角) or different nsors(传感器) to obtain.Explain alone nsors You can understand for the camera,next,I explain the keywords of This ntence,overlap We deal with the image must be Share a common area;for example(看图像)，The two images,Underlined that they overlap,If there is no overlap, computer will occur stitching error.Seamless and high-resolution we get Stitching images,it is clearly and no Stitching line,for example(看图像)，In this image, we can't e any stitching marks.We know the image stitching,

4、next，Let me talk about the meaning of image stitching,Image stitching technology is widely ud in many field.
In the field of remote nsing(遥感)，the digital image stitching technology deals with remote nsing images that Satellite or plane collected.it Joined together into a completely and clearly of remote nsing images.Thus,Convenient relevant staff for further analysis of the remote nsing images;
In the field of medicine,a complete brain cells panoramic image (脑细胞全景图)can be beneficial to the doctor analysis with the lesion site of patient spread , so as to make better treatment scheme;
In addition,in the field of statistics,image stitching technology is applied in the agricultural cultivated land area and food crops statistics. Underwater detection(水底探测青岛留学>英文谷歌) and virtual tourism（虚拟旅游）考虑的英文 and so on.one picture is worth a thousand words,meritoriouslet’s e()The specific application of image stitching.The five images is aerial graph of the Palace Muum,Obviously,They are the part of the Palace Muum,Put them together, make up
i still believe 歌词the whole panorama of Palace Muum.
6、When we understand the meaning of image stitching ,let me take about How to complete the image stitching Usually,Image stitching includes：image acquisition(图像获取)、image preprocessing（图像预处理）、英语六级考试技巧image matching（图像配准）armor, image fusion（图像融合）。
The image matching and fusion is the key to the whole process.My design is as follows： ,1 2 3is belong to image is belong to image fusion.Next, I explain in detail the important method.firstly,Why choo sift algorithm.
7\ Let's look at this picture.We guess whether they belong to the same image.In fact, they belong to the same image just photograph Angle different.In order to deal with in the process of image matching caud by the location of the image changes of error.We cho to sift.
8\SIFT algorithm is also called Scale Invariant Feature Transform (尺度不变特征转换)met
hod, is a kind of local feature extraction method.Using sift algorithm can effectively resolve the error that Due to the image position changes.its principle is as follows:
9\Image matching is completed, the next is the image fusion,in image fusion I cho weighted average algorithm,why?becau,this algorithm less calculation and the fusion effect is good.Its principle is as follows:
Where i is the line of pixels of the image quence (I = 1, 2, 3... I), j is the column of pixels of the image quence (j = 1, 2, 3... j). ω1 and ω2 is weighted coefficient. If ω1=,the fusion of image1 and image2 is weighted average fusion.
11\My report finished,Thanks for your listening ! Any question!
