A procedure for logo watermarking of speech signals is proposed. In order to take full advantage of both time and frequency domain, we have used joint time-frequency representation of speech signal, which provides a more comprehensive information compared to each domain individually. Time-frequency based selection of the Discrete Fourier Transform (DFT) coefficients is used for logo embedding. ...

A video logo is usually a declaration of the video copyright. However it sometimes causes visual discomfort due to the presence of multiple logos in videos that have been filed and exchanged by different channels. In this paper, we present an approach to erase logos from video clips. Based on the histogram energy analysis of the relevant video frames, we obtain the best quality logo frame that ...

In this snapshot, Wally Feurzeig, one of the originators of Logo, and an innovative designer of mathematics education learning environments, recalls some compelling vignettes from the early history of Logo (including activities with the first Logo-controlled wireless turtle), with children ranging in age from pre-schoolers to fifth-graders. Wally passed away this past year. Wally was a long-tim...

In this paper, we present a connectionist approach for detecting and precisely localizing transparent logos in TV programs. Our system automatically synthesizes simple problem-specific feature extractors from a training set of logo images, without making any assumptions or using any hand-made design concerning the features to extract or the areas of the logo pattern to analyze. We present in de...

This study evaluated the effect of Logo programming in enhancing creativity skills. Eighty five fifth-grade students were assigned to experimental and control groups. A pre-test was administered to assess figural creativity factors consisting of receptive fluency, flexibility, originality and elaboration. After eight weeks of Logo programming learning, the experimental group had significantly h...

The vehicle driving cycles affect the performance of a hybrid vehicle control strategy, as a result, the overall performance of the vehicle, such as fuel consumption and emission. By identifying the driving cycles of a vehicle, the control system is able to dynamically change the control strategy (or parameters) to the best one to adapt to the changes of vehicle driving patterns. This paper stu...

The Vehicle Licence plate Detection Method has many applications like cars parking in hotels, traffic signal violation, electronic toll collections and border crossing vehicle etc. Any detection method has some major challenges like Licences plates have arbitrary sizes, orientations, complex backgrounds and localization of licence plates. In this paper a new vehicle licence plate detection meth...

Abstract In this paper a wavelet-based logo watermarking scheme is presented. The logo watermark is embedded into all sub-blocks of the LLn sub-band of the transformed host image, using quantization technique. Extracted logos from all sub-blocks are merged to make the extracted watermark from distorted watermarked image. Knowing the quantization step-size, dimensions of logo and the level of wa...

With technology of digital image recognition, the data frames include vehicle’s digital image can be detected automatically from an Audio Video Interleaved (AVI) File, and vehicle type will be recognized automatically. The system consists of four modules: Reading AVI file and decomposing it into digital image frames; Motion detection; Vehicle’s digital image processing; Module of vehicle type c...
