Sketch-based Image Retrieval Technology Clothing And System Implementation

Based on the rapid development of the information stored in the Internet era of multimedia digital multimedia technology makes increasingly large, and thus the image management and storage of many scholars have become an important research topic. After years of in-depth research in the field of content-based image retrieval technology we have made remarkable achievements.Content-based And Text-based retrieval technology has a great difference based. Text retrieval based image retrieval technology to meet the requirements is to search for images based on keywords entered by the user. However, due to the different users keyword text subjectivity is not necessarily accurate, leading to the search results received. The content-based image retrieval technology a more complete solution to this problem, do not rely on keywords, the painted image as user input, based on the image content objects outside contour lines feature for feature extraction expression models, the corresponding matching algorithm, so a lot of pictures to match the database, retrieves the image to achieve full content screening the target, found with similar images.Meanwhile, in recent years, touch input device smart phones, tablet computers in our lives occupy the mainstream position, so that human interaction a major shift in the way. People in the touch-screen operation mode, can be more accurately and easily through the painted object manifested want to express, and then hand-painted by line drawings found with a similar shape as in a large number of gallery. With such pen-based interface technology for real-time retrieval operation in line with the user's thinking and habits, but also easy for users to describe the target image retrieval.Content-based image retrieval in the field of clothing also used widely. After checking the relevant information we can see that the color, pattern and style are three characteristics the most essential clothing[1]. The sketch is the costume design for a class of shape relatively efficient information carriers, in currently available clothing style design flow diagram, clothing styles to complete structural design is based on the style name or number to deposit the document. Designers will design pattern based on the existing version of the type or general basis, since clothing styles can all be adjusted accordingly in the basic structure pattern to reach the final pattern structure, if only to describe the text style marked lack of intuitiveness, more limited, such as in the form of an image as a search condition may reduce operating efficiency. Therefore, in order to improve the efficiency of designer clothing styles designed to improve existing traditional SURF feature matching algorithm improves the retrieval efficiency, designed and implemented a costume sketch-based image retrieval system.The main difficulty of the garment image retrieval system based on sketch is reflected in the following aspects: changing the original SURF algorithm to extract the features of the garment structure description,the consistency of the feature extraction and description between the sketch and the sample image, The efficiency of large-scale database retrieval, improve the retrieval speed while keeping the large data base unchanged, change the transmission mode of mobile client and network server, more efficient and convenient.System innovation is reflected in the following aspects: the hand-drawn sketch-based image retrieval technology and clothing creative combination, break through the traditional hand-drawn sketch feature extraction algorithm, the clothing structure to join the feature description,preliminary and gradually systematically The establishment of a large-scale clothing-based features of the database.The size of the drawing area is provided with some sketch-based clothing image retrieval system(Sketch Based ClothesImageRetrieval, SBCIR) system interface, the user can draw a sketch and retrieval system showed the list of responses to the system provided. In parametric design has been widely applied to the field under garment production trends, fashion designers can reduce a lot of unnecessary repetitive operations, improve production efficiency.
