In this paper, we present a near real time approach to lane detection in highway and urban streets using images captured from monocular cameras as an input. The proposed method includes four main steps. First, the input image is transformed to a bird's eye view image by using warp perspective mapping. Second, an edge image is produced by applying a custom edge detection and morphology operation on...
This paper proposes three robust detection algorithms for locating the cutting line in an image captured by a panel-cutting system. All of the proposed methods contain two stages: edge detection and line fitting. In this paper, edge detection can search interest gradients depending on the intensity concentration. Meanwhile, the proposed line-fitting algorithm is able to precisely fit a line by minimizing...
This paper presents superpixel-based background removal methods to increase accuracy of global salience person re-identication method. The current algorithm has two problems which limit its accuracy including (1) wrong matching when images of different people have the same background and/or (2) salience on the background of different images of different people is similar. Theoretical maximum accuracy...
This paper proposes a new method to detect static caption regions using intensity range maps and a statistical model of motion vectors. The method relies on the probability of block-based intensity ranges and magnitudes of motion vectors. Intensity range is used to find candidate locations of static captions and the statistical model of motion vector is used to refine accurate caption regions. The...

Distortion in images is a biggest challenge now-a-days. This affects in many areas ranging from photography to medical imaging, astronomy, remote sensing and microscopy. Images get obscured due to many reasons like vibration due to hand movement as well as launch of vehicle (Satellite), Noise in image, Adverse Image/Environment condition, and Quick movement of objects. A technique is required which...
Evolving graphs arise in problems where interrelations between data change over time. We present a breadth first search (BFS) algorithm for evolving graphs that computes the most direct influences between nodes at two different times. Using simple examples, we show that naive unfoldings of adjacency matrices miscount the number of temporal paths. By mapping an evolving graph to an adjacency matrix...
Different filter methods to reduce noises occurred during image capture have been developed. One of the most effective image filters is diffusion filter. However, the major drawback of conventional diffusion filter is user-dependent. While noises are reduced with conductance coefficient arbitrarily selected, edge pixels are perceived such as noise. In this study, a novel anisotropic diffusion filter...
In the current era of technology advancements, the number of digital transmission libraries are growing terribly quickly, the necessity to expeditiously index, browse and retrieve transmission data is hyperbolic. In this paper, a technical analysis on textual data identification and extraction from image is given in which various approaches for text detection and extraction are discussed and an evaluation...
Shadow cause some unwanted change in computer vision and image analysis. Shadow leads to problems in extraction, segmentation of object and recognition due to the misclassification of shadow points as foreground or object points. So, the detection of shadow is of broad interest in computer vision. Due to the alteration in illumination of the background and similarity between appearance of the objects...
Peer to peer and distributed systems are generally susceptible to sybil attacks. Online social networks (OSNs), due to their fat user base and open access nature are also prone to such attacks. Current state-of-art algorithms for sybil attack detection make use of the inherent social graph created among registered users of OSN service. They rely on the inherent trust relationship among these users...
In this paper, we propose an improved dynamic gamma correction method to enhance contrast and image quality for Liquid Crystal Displays (LCD) with Multi-Phosphor White Light Emitting Diodes (MPW LED). In order to reduce the hardware cost and improve the contrast and the edge strength, the proposed gamma correction method uses content-based analysis to reduce computational complexity. Experimental...
This paper proposes a new method for the application of makeup on the eyes, face, and lips based on several makeup examples. We created two Gaussian weight maps to generate the effect of natural skin makeup. Due to our Gaussian weight map in blending process, our makeup results are natural.
We propose a pixel similarity based Betacam dropout detection method. Proposed method aims at detecting errors, having vertically similar pattern without considering sequential frame when archiving a tape-based content to a file-based system. Moreover, this method works along with a real-time instant Quality Control(QC) system with less false-alarm.
This paper proposes a multiview synthesis method for autostereoscopic (glasses-free) 3D displays. When a plurality of predetermined viewpoint images is generated from a limited number of input images, background information obscured by a foreground object in the input images may be represented by a hole in a new viewpoint image. The proposed method can restore the hole in the image while leaving structural...
In this paper, we propose a novel image segmentation algorithm for license plate recognition (LPR) in video based traffic surveillance system. The license plate character segmentation is most important procedure in LPR system. However, in real situation, the character segmentation algorithms are challenged by drastic performance decrease due to sudden local illumination changes, especially when the...
Images taken in low-light environments are often degraded due to camera shake and pixel saturation. In this paper, a motion deblurring method for non-uniform blur is proposed, in which an optimization problem is formulated using a maximum a posteriori approach. In the final deconvolution process, a modified Richardson-Lucy algorithm with regularization is used to reduce ringing artifacts and noise,...
In this paper we propose a novel method to improve the performance of image retrieval at VLAD (Vector of Locally Aggregated Descriptors) level. Our re-ranking algorithm uses relational graphs and the top-& neighborhood candidates to adaptively modify images similarity scores. The method is effective and increases the accuracy, without relying on low-level information or features geometrical verification.
Curvature, the second-order directional derivative of an image, has been widely used for image interpolation. However, conventional curvature-based interpolation (CBI) methods employ a time-consuming post processing to reduce visual artifacts such as blurring and jagging caused by the inaccurate estimation of the local curvature. In this paper, a novel fast CBI method is proposed which can precisely...
Lane departure warning (LDW) systems have gained a lot of interest over the last few years. EuroNCAP regulations mandate European car makers to have LDW system to get star rating. In this paper, we propose a simple image-based implementation of LDW system optimized for the Texas Instruments (TI) C66x Digital Signal Processor (DSP). We show that our solution is able to overcome certain challenges faced...
