A new cluster-based method for several lines detection is proposed. Abstract This paper proposes a new efficient method for line detection based on known incremental methods of searching for an approximate globally optimal partition of a set of data points A and on the DIRECT algorithm for global optimization.
Brightness and Contrast values apply changes to the input image. They are not absolute settings.
A brightness or contrast value of zero means no change. Positive values increase the brightness or contrast and negative values decrease the brightness or contrast.
The default is to apply the same transformation to all channels. Brightness and Contrast arguments are converted to offset and slope of a linear transform and applied using -function polynomial "slope,offset". All achievable slopes are zero or positive. The offset varies from The default thresholds are shown.
The radiusxsigma controls a gaussian blur applied to the input image to reduce noise and smooth the edges. This option sets the caption meta-data of an image read in after this option has been given.
To modify a caption of images already in memory use " -set caption". The caption can contain special format characters listed in the Format and Print Image Properties.
These attributes are expanded when the caption is finally assigned to the individual images. If the first character of string isthe image caption is read from a file titled by the remaining characters in the string. Comments read in from a file are literal; no embedded formatting characters are recognized.
Caption meta-data is not visible on the image itself.
To do that use the -annotate or -draw options instead. Here is an example color correction collection: The numerals 0 to 31 may also be used to specify channels, where 0 to 5 are: Not all operators are 'channel capable', but generally any operators that are generally 'grey-scale' image operators, will understand this setting.
See individual operator documentation.Abstract. Abstract- An integral component of Autonomous Driver Assistance system is the robust detection and tracking of lane markings.
It is a rigid problem due to large appearance variations in lane markings caused by factors such as improper illumination (transition from day to night), occlusion (traffic on the road), shadows from objects, etc.

HOUGH TRANSFORM BASED LANE DETECTION A. Hough Transform- An Overview– Hough Transform (HT) [2, 7] is a method to detect uninformed shapes in images, given a parameterized description of the shape in problem.
Set the drawing transformation matrix for combined rotating and scaling. This option sets a transformation matrix, for use by subsequent -draw or -transform options..
