Abstract: A semiconductor device includes a vertical column of wire bonds on substrate contact fingers of the device. Semiconductor dies are mounted on a substrate, and electrically coupled to the substrate such that groups of semiconductor dies may have bond wires extending to the same contact finger on the substrate. By bonding those wires to the contact finger in a vertical column, as opposed to separate, side-by-side wire bonds on the contact finger, an area of the contact finger may be reduced.

Abstract: Facial skin mask generated by a digital content creation system is described. The digital content creation system includes digital effects on skin in facial regions of digital content with efficiency and accuracy. Upon identifying a facial region within digital content, the system generates a first regional skin mask, a second regional skin mask, and combines both of the first and second regional skin masks to generate a facial skin mask indicative of skin of the identified facial regions depicted in digital content. The digital content creation system then modifies digital content by applying user selected digital effects to the skin of the facial region using the generated facial skin mask.

Abstract: In some embodiments, an image manipulation application receives an incomplete image that includes a hole area lacking image content. The image manipulation application applies a contour detection operation to the incomplete image to detect an incomplete contour of a foreground object in the incomplete image. The hole area prevents the contour detection operation from detecting a completed contour of the foreground object. The image manipulation application further applies a contour completion model to the incomplete contour and the incomplete image to generate the completed contour for the foreground object. Based on the completed contour and the incomplete image, the image manipulation application generates image content for the hole area to generate a completed image.

In various embodiments, a service request for invoking the meta service is received, where the service request matches metadata of the meta service. In those embodiments, the service request is converted into a cloud service request packet based on metadata of a cloud service corresponding to the meta service, where the cloud service request packet matches the metadata of the meta service. Still in those embodiments, the cloud service request packet is sent to invoke the cloud service, and a cloud service response packet is received, where the cloud service response packet is an invocation result obtained by invoking the cloud service. Also in those embodiments, the cloud service response packet is then converted into a service response that matches the metadata of the meta service and sending the service response.

Abstract: Disclosed herein are embodiments of systems, methods, and products for a webly supervised training of a convolutional neural network (CNN) to predict emotion in images. A computer may query one or more image repositories using search keywords generated based on the tertiary emotion classes of Parrott's emotion wheel. The computer may filter images received in response to the query to generate a weakly labeled training dataset labels associated with the images that are noisy or wrong may be cleaned prior to training of the CNN. The computer may iteratively train the CNN leveraging the hierarchy of emotion classes by increasing the complexity of the labels (tags) for each iteration. Such curriculum guided training may generate a trained CNN that is more accurate than the conventionally trained neural networks.
