Object Extraction in Optical Measurement Image Based on the Channel Module in Photoshop

Abstract

Object extracting and optical measurement of the image is researched by using the Photoshop channel module as the operating platform, and a simple and practical processing method of optical measurement image was proposed. Hereby, the optical measurement image process and the relationship between channels module and constituency is analyzed, and the method of object extraction in optical measurement image by Photoshop is studied. The image processing result shows that the object extraction based on channel module in Photoshop is an effective method. Introduction The application of digital image in human life is more and more widely, and digital image processing technology is more and more professional and mature. Digital image processing technology mainly includes modifying the graphics, improving the quality of the image, or extracting the effective information from the image. The mainly method of digital image processing includes: Fourier transform, the wavelet transform, various image transform, image coding and compression, using a variety of methods for image restoration and enhancement, segmentation and description and recognition of image etc. However, the above mentioned multiple methods or techniques are required for strong professional knowledge. Generally, digital staff cannot yet accomplish this work. The goal of this paper is to explore its feasibility in optical image object extraction and validate in the use of Photoshop in powerful channel function, which is in order to find a simple and practical method for optical image processing. It found in the practical application that it can be very good to complete the object extraction in optical measurement image based on the channel module in Photoshop. Photoshop technology for object extraction The Adobe Photoshop is a graphic image processing tool. Adobe Company launched across the PC and MAC two interfaces and it is the leading large-scale image processing software. Photoshop has many cutout methods, including the basic selection tool cutout, pen tool cutout, filter cutout, mask cutout, and set the blend mode cutout, Alpha channel cutout, channel cutout, plug-in cutout, etc. Light measuring image object of the target extraction and Photoshop cutout technology on connotation is consistent. It can pick the target up from the background, so the light measuring image object extraction is feasible by using Photoshop. Photoshop channel module principle analysis In Photoshop, the channel is used to store the information of image color and custom selection. Not only you can get very special districts to use the channel to aid drawing, and also you can change the color information that deposited in the channel in order to adjust image color. Whether you open a new file or scanned document, when an image is inserting into Photoshop, Photoshop can create an image file for its natural channel--members channel or color channel, the primary channel’s number depends on the color of the image pattern. Channel principle: an image of RGB mode based on red, green and blue three primary colors. In
