This paper presents an imageprocessing approach to extract six features of the probe mark on semiconductor wafer pads. The electrical characteristics of the chip pad must be tested using a probing needle before wire-bonding to the wafer. However, this test leaves probe marks on the pad. A large probe mark area results in poor adhesion forces at the bond ball of the pad, thus leading to undesirable products. In this paper, we present a method to extract six features of the wafer probe marks in IC packaging for further digital imageprocessing.

This paper discusses an outdoor guidance system that can be implemented on a smartphone. The purpose of such a system would be to assist the blind or visually impaired. The system will be able to detect the ground, find obstacles, and notify the user when the obstacle is close enough to constitute a tripping hazard. This work uses a novel semantic segmentation technique and proposes an alternate method for positioning the phone for better fall prevention techniques.

These systems are based on images uploaded by users. They first determine the most similar users based on the images they upload to the system. They then return the most likely image to the users based on the images liked by the neighbors. The most challenging problem in image-based recommneder systems is to match an image with the most similar visual words or classes based on the image's visual content. We design a system which is using Bag of words model, to solving this problem.1 BoW model is an effective model in computervision field, and we use SURF, SIFT and LBP descriptors for extracting features in our system.

In the recent years, many breakthroughs are made in the imageprocessing Technology, particularly in areas like satellite imaging and biometrics. This paper presents an experimental approach of vision based surface roughness measuring system using speckle images produced by a line laser beam on milled surfaces. A CCD Camera, line laser source and white light were used for capture the images of milled surfaces. A signal vector was obtained from image pixel intensity and it was processed using MATLAB software. Mean and standard deviation are the two parameters used to characterise the image signal vector. The roughness of the specimens, particularly the Arithmetic mean slope (R-da) are computed using a stylus instrument. From the experiments, it is found that mean intensity of the signal vector of the speckle line images correlate well with R-da values of the surface roughness. Hence, the mean image intensity value of speckle line images has a strong potential for the online characterisation of surfaces.
Scene classification makes it easier to semantic scene understanding and aids to further processes and inference, using an assignment of pre-defined classes. Under this motive, we proposed an approach to classify indo...
