| Popis: | The task of image segmentation remains a fundamental challenge, in the field of computer vision. Convolutional Neural Networks (CNNs) have achieved significant success in this field, yet there are some limitations in the conventional approach. The process of accurate, pixel-wise image annotation is time-consuming, as well as requires more human effort. These problems are addressed by the proposed method called as Percept-CNN (P-CNN), which extracts the power of percepts, pixels responsible for the higher activations at each level. From each layer, percepts are extracted during the forward propagation. These percepts are then passed onto the subsequent layers, enabling the model to focus only on the useful visual information. The proposed method with Percept Convolution can potentially eliminate the complex and time-consuming task of image annotation without affecting the segmentation accuracy. Since the model focuses only on the useful salient visual information, it tends to reduce the extraction of the redundant features, which doesn’t really contribute towards the final goal. This makes the model to be more robust, accurate and efficient. The proposed model was able to perform semantic segmentation without pixelwise annotations with an accuracy of 67% when tested on Oxford IIIT pet dataset. |
