marcosgdiaz / SignalProcessingHere, I compile some of my work during my last year of bachelor, when I was involved in a research group. Basically, it consists on receiving data from a radar embedded in a drone and applying SAR (Synthetic-Aperture Radar) algorithms. Besides the SAR algorithms, I have tested several preprocessing techniques like frequency equalization and domain partition in order to improve the final image.
fitushar / Skin Lesion Segmentation Using GrabcutSkin lesion segmentation is one of the first steps towards automatic Computer-Aided Diagnosis of skin cancer. Vast variety in the appearance of the skin lesion makes this task very challenging. The contribution of this paper is to apply a power foreground extraction technique called GrabCut for automatic skin lesion segmentation in HSV color space with minimal human interaction. Preprocessing was performed for removing the outer black border. Jaccard Index was measured to evaluate the performance of the segmentation method. On average, 0.71 Jaccard Index was achieved on 1000 images from ISIC challenge 2017 Training Dataset.

KishanRamoliya / Histogram Equalization Logarithmic Mapping Image Rotation Gaussian Averaging Filter Median FilterImplementation of Histogram Equalization, Logarithmic Mapping, Image Rotation, Gaussian Averaging Filter and Median Filter. Histogram equalization is a method using which we can adjust image intensities that will enhance the contrast of the image. By applying the histogram, the intensities of the image can be distributed properly which will allow the area with lower contrast to gain proper higher contrast. To compress the dynamic range of an image we can replace each and every pixel value with their log values. By implementing this, we enhance the low intensity pixels of the image. Logarithmic mapping is a simple point process in which the mapping function is a log curve. Since the logarithm is not defined for, the equation of the log mapping function looks like given below: 𝐼′(𝑟,𝑐)=log(𝐼(𝑟,𝑐)+1). Rotation is the operation that will perform the geometric transformation of the image element which will be rotated at the given angle about an origin. Gaussian filter have a special type of property of not having any overshoot towards a step input function and it minimizes the fall and rise time, thus it has minimum delay in group. Due to this property the Gaussian filter is considered the ideal time domain filter. Median filter is basically used to remove the nonlinear noise in the images. Generally this is used in the preprocessing step in different image processing algorithms. The most significant reason to use the median filtering is that it preserves the edge information even after removing the nonlinear noise.

shubham-1123 / Seizure Detection Using CNN On EEG DataElectroencephalogram(EEG) benchmark dataset Chb-mit is used for seizure detection. The CHB-MIT dataset is a publicly available database that contains data from 24 patients. Each patient has many seizure and non-seizure recording files in European data format (.edf). The majority of EEG signals are recorded using 23 channels at a sampling rate of 256 Hz. These signals also contain noise. So EEG signals must be preprocessed before being analysed. A Butter-Worth bandpass filter for removal of undesired noise and various artefacts, where low cut-off frequency is considered as 0.5Hz and high cut-off frequency is considered as 30Hz. EEG signals are segmented into images of window size of 1 sec.And CNN model is applied onto segmented images and the model is trained and tested on four parameters: accuracy , sensitivity , specificity and f1-score.
