After more than ten years of development, with the overall costs have been declining constantly being upgraded and improved, applications continue to expand, leading standard surgery and the development of liquid crystal display trendsetter, so Samsung commercial LCD has many of the world's leading commercial product and solutions, and in monitoring, multimedia advertising and public information dissemination, three-dimensional imaging system in many fields, such as video conferencing and achieved huge success. Samsung LCD Video Wall is actively committed to leading liquid crystal display technology, continued to expand public information display, many commercial areas of security monitoring, video conferencing, through professional display equipment and complete solutions to serve the information construction of Chinese society . With the development of technology, the LCD splicing screen, large-screen video wall application products more widely, its huge, bright display feels impeccable, the only fly in the ointment is flawed gap. Here we learn with Yu Tian Chen Technology engineers recipe for the most effective addition to sewing techniques. LCD splicing dismiss a lot of sewing skills, the most effective techniques are; wavelet transform method, median filtering method, the weighted average method. 1. Eliminate the seam - wavelet transform the wavelet transform is now more common method, he take advantage of multi-resolution characteristics of wavelet transform, a good solution to the problem of image mosaic seams. The principle is: Because the wavelet transform has properties band-pass filter, wavelet transform components at different scales, in fact, occupy a certain bandwidth, the greater the scale j, the higher the frequency of the component, so that each component of the wavelet have little bandwidth, the two images to be spliced ??press wavelet decomposition method to decompose them into wavelet components at different frequencies, so long as the decomposition was fine enough bandwidth wavelet components can be sufficiently small. Then at different scales, select a different stitching width, the two images at different scales by wavelet components of the first fight next, and then use the recovery process to restore the entire image. Thus obtained can be a good balance between image sharpness and smoothness of two requirements. However, there are also disadvantages wavelet transform, such as wavelet transform algorithm is more complex, you need to first wavelet transform domain splicing process, involving a large number of floating-point operations and border deal with the problem in the calculation process, the actual production of large-volume image When processing computer memory is expensive and takes a long time, stitching slow. 2, to eliminate the seam - median filter median filter is the seam area near the median filter. The gray value of the surrounding pixels take a relatively large difference with the surrounding pixel values ??closer to eliminate light intensity discontinuities. Median filter processing Panhandle vicinity of the seam. This method faster, but the quality in general. Smooth resolution of the image result will fall, so that the image can not tell the details, produce blurred images. 3, eliminate the seam - weighted smoothing method in practice, using more methods there are overlapping areas of weighted smoothing method. Thinking of this method is: the image overlapping area Pixel pixel gray scale values ??in the two images and gray-point value LPixel RPixel weighted average correspond, namely: Pixel a kXLPixel + (l a k) XRPixel which: k is the gradient factor, the condition: When looking for the best seam line, using a sliding window on the images overlap area progressive select the smallest gray value difference of pixels as the best splice point. However, if the splice point in this selection method, there will be a new problem that often appear down the line splice position far behind the phenomenon, after this gray stitching sometimes because a large difference between the top and bottom line and creating new seams. In order to avoid this kind of phenomenon, not only to consider the differences between the gray values ??of adjacent splice points, but also consider the location of the adjacent splice point can not be too far away. This introduces a Lanna value T, to select the best splice point limit the scope of this Lanna value. In addition to the first line according to the principle of gray value difference between the minimum processing, the splice points of the other lines selected from a selected area: Point and the previous line splice point with selected columns and to the point as the center of the horizontal width T region point. Select one of the best splice point in this area. After the election of each line splice point connections into a seam line, you can imagine, this might be a broken line stitching line. Thus, since the line is to select the prescribed neighborhood gray difference between the minimum point as the splice points, seams phenomenon will be greatly improved. Meanwhile, the value of T has not chosen to be too large to be between 1 to 5 to select preferred. After finding the best LCD splicing gap, weighted aforementioned smooth transition to the overlapping area and then, the resulting image quality is greatly improved.
