Detection and classification of road signs in raining condition with limited dataset

چکیده
The road sign recognition (RSR) system is used to complete two tasks: localizing the traffic in an image and then classifying it according features. Some of applications such are incorporated into Advanced Driver Assistance System (ADAS) autonomous vehicles. However, accuracy model decreases when changes lighting or weather occurs, lack training samples taken rainy condition causes be sub-optimal. research was conducted with focus on solving problems, object detection data, especially images under adverse condition. In this work, we compare analyze three methods; automatic white balance (AWB), policy augmentations Image-to-Image-translation (I2IT) technique their performance detect signs raining conditions. All methods were built upon pre-trained SSD-MobileNetV2 using TensorFlow2 framework. from Malaysia Traffic Sign Dataset (MTSD) train all models. Finally based result a final combination proposed that achieved best Experimental results showed AWB not effective detecting condition, while other techniques highly effective. implemented by combining augmentation I2IT, obtained mAP 0.7967 clear 0.7160 added testing dataset. These corresponds at 50% IoU [email protected] during [email protected] images, which outperformed Thus, classification can perform well limited dataset has been successfully developed.

Road Detection by One-Class Color Classification: Dataset and Experiments
Detecting traversable road areas ahead a moving vehicle is a key process for modern autonomous driving systems. A common approach to road detection consists of exploiting color features to classify pixels as road or background. These algorithms reduce the effect of lighting variations and weather conditions by exploiting the discriminant/invariant properties of different color representations. ...

در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
Incremental detection of text on road signs
This paper presents a framework for incremental detection of text from road signs. The approach efficiently incorporates tracking and detection mechanisms into the same framework. The proposed approach first finds a set of discriminative feature points and clusters them into different regions. We then select candidate sign planes by a combination of color and vertical plane models. Within detec...
