What are the vector file formats? Vector graphics are commonly found today in the SVG, EPS and PDF graphic file formats and are intrinsically different from the more common raster graphics file formats of JPEG, PNG, APNG, GIF, and MPEG4. AI filename extension is used by Adobe Illustrator. The AI file is a vector file? Adobe Illustrator Artwork ( AI) is a proprietary file format developed by Adobe Systems for representing single-page vector-based drawings in either the EPS or PDF formats. An EPS file can contain text as well as graphics. Four experiments are conducted to test the proposed algorithm and results with superior precision and reliability show the feasibility and effectiveness of the proposed method for the velocity measurement accuracy of a vehicle relative to the ground.What is a vector EPS file? Encapsulated Postscript Vector graphics (Adobe Illustrator) EPS is a file extension for a graphics file format used in vector-based images in Adobe Illustrator. The prominent advantages of the proposed algorithm are: (i) increase the velocity measurement accuracy of a vehicle relative to the ground (ii) use the information of color images acquired with cameras thoroughly and obtain velocity calculation outputs with less fluctuation (iii) reduce wrong values caused by noises that are from the origin image and introduced by similar color masks.
Finally, the velocity is calculated by the optical flow value. Based on the gray consistency method, the optical flow can be obtained by the pyramid LK algorithm. Then images are decomposed into three channels, red, green, and blue (i.e., $R$, $G$, and $B$), and processed by median filter. First, a mask region with convolutional neural network (Mask-R-CNN) is used to recognize the objects that have motions relative to the ground, and it covers them with masks to enhance the similarity between pixels and to reduce the impacts of the noisy moving pixels. In order to reduce the effects caused by moving objects, this paper integrates pyramid Lucas–Kanade (LK) algorithm with the gray consistency method to use the information of color images thoroughly. However, when there are moving objects on the stationary ground, the interfering optical flow field will be generated, which decreases the velocity measurement accuracy of a vehicle relative to the ground. The optical flow method has been widely used to measure the vehicle velocity by observing the stationary ground with a camera looking-down.
Keep it simple - don't use too many different parameters.
