Automated Digital Conversion of Hand-Drawn Plots

نویسنده

چکیده

An algorithm has been developed using Matlab that takes an image of a sketch of one or more functions, plotted on the xand yaxes, and converts it into an electronic plot, along with the set of equations and parameters that recreate the same plot. This is accomplished by extraction of the plot data, followed by data grouping based on three different heuristic methods (colour, slope and process of elimination), followed by leastsquares fitting. Keywords-graph; plot; sketch; digitization; conversion

Freehand Drawing vs. Transformed Digital Drawing: A Preliminary Study and Comparison

This paper presents a preliminary study and comparison of digital drawings, which are transformed from freehand sketching by using Photoshop. With the development of new software, digital drawings are used more and more extensively in the design field. However, freehand sketching continues to provide unique and vital capabilities to interior designers and architects in allied fields (Laseau, 20...

Automated Methods for Estimating Baseflow from Streamflow Records in a Semi Arid Watershed

Understanding of the runoff generation processes is important in understanding the magnitude and dynamics ofgroundwater discharge. However, these processes continue to be difficult to quantify and conceptualize. In this study,two digital filter based separation modules, the Recursive filtering method (RDF) and a generalization of therecursive digital filter (GRDF) were1991–2002 in the Hableh Ro...

Generation of Slides from Hand-Drawn Sketches

As engineers, we often find ourselves spending a non-trivial amount of time converting sketched diagrams and figures into digital format. A lot of research has been done in conversion of hand-drawn sketches to computer drawings. However, most of it is domain-specific with training templates which must first demonstrate the shapes the user first intends to recognize as suggested by Kara and Stah...

Improving adaptive resolution of analog to digital converters using least squares mean method

This paper presents an adaptive digital resolution improvement method for extrapolating and recursive analog-to-digital converters (ADCs). The presented adaptively enhanced ADC (AE-ADC) digitally estimates the digital equivalent of the input signal by utilizing an adaptive digital filter (ADF). The least mean squares (LMS) algorithm also determines the coefficients of the ADF block. In this sch...

Color Reduction in Hand-drawn Persian Carpet Cartoons before Discretization using image segmentation and finding edgy regions

In this paper, we present a method for color reduction of Persian carpet cartoons that increases both speed and accuracy of editing. Carpet cartoons are in two categories: machine-printed and hand-drawn. Hand-drawn cartoons are divided into two groups: before and after discretization. The purpose of this study is color reduction of hand-drawn cartoons before discretization. The proposed algorit...
