A vehicle logo occupies a small proportion of car and has different shapes. These characteristics bring difficulties to machine-vision-based detection. To improve the accuracy detection in complex backgrounds, an improved YOLOv4 model was presented. Firstly, CSPDenseNet introduced backbone feature extraction network, shallow output layer added replenish information target. Then, deformable conv...

In this paper we propose an adaptive model, referred to as Recursive Neural Networks (RRNNs) for logo recognition by explicitly conveying logo item intom-ary tree representation, where symbolic and sub-symbolic information coexist. Each node in the contourtree is associated with an exterior or interior contour extracted from the logo instance. A feature vector, which includes the perimeter of t...

One of the strongest clues for retrieval of content information from complex document images is logo. However, due to the wide range of transformations that an object might undergo, this is also the most difficult one to handle. Logo retrieval is one of the major barriers now a days for image databases being commonly used. Automatic logo detection and recognition continues to be of great intere...

This paper proposes an automated system for rotation and scale invariant color logo recognition. Colored logo images are recognized using one shape feature namely Moments Invariant and a color feature namely Color Moments. Shape of the logo is modeled using the first two central normalized Hu's invariant moments while color is modeled using the mean, standard deviation, skewness and kurtos...

In the past few years many offices maintained their documents in printed form, as this the volume of printed documents were increased they suffered from a problems like space to keep them and searching of particular document. Due to this reason and due to advances in information technology made the offices to keep their documents in image form, but even though they faced a problem of retrieving...

DIRECT-INFO is a system for media monitoring applied to the field of sponsorship tracking. Significant parts of TV streams and electronic press feeds are automatically selected and subsequently monitored to find appearances of the name or logo of a sponsoring company in connection with the sponsored party. For this purpose basic features are fully automatically extracted from TV and press and t...

Brand elements, including: brand name, logo, slogan, colors, jingles and characters, can be considered as important determinants of brand awareness and brand image (Keller 1998; Schmitt 2000). In this study we investigate the effects of logo design characteristics on brand recognition and effect in the Chilean market. The overall conclusion is that the logo design characteristics (harmony, para...
