Abstract: An approach to identifying text within an image may be presented. The approach can receive an image. The approach can classify an image on a pixel-by-pixel basis whether the pixel is text. The approach can generate bounding boxes around groups of pixels that are classified as text. The approach can mask sections of an image that where pixels are not classified as text. The approach may be used as a pre-processing technique for optical character recognition in documents, scanned images, or still images.

Abstract: Machines, systems and methods for allocating resources to in a virtualized computing environment, the method comprising detecting one or more host machines with resources allocated to one or more virtual machines (VMs) that are in an idle state; reducing resource entitlements for at least one of the VMs that is detected to be in the idle state to make more resources available for allocation to VMs that are not in the idle state; and increasing resource entitlements for at least one of the VMs with reduced entitlement, in response to determining that the VM with reduced entitlement is no longer in the idle state.

Abstract: A revision control service is included in a hypervisor. The revision control service manages revision control operations relating virtual machine images transparently to the virtual machine. The revision control service interacts with a conventional revision control program, stores relevant revision control metadata external to the virtual machine image with file-level granularity, and synchronizes virtual machine operations with the revision control operations. From the perspective of the virtual machine, the revision control service provides a clean image from which to boot, without modification of the revision control program.

Abstract: A system and method for creating N customized disk images from N identical disk images. A computing system creates N identical disk images from a master image. The computing system customize a first identical disk image according to a customization written in customization scripts. While customizing the first identical disk image, the computing system monitors block-level operations applied on the first identical disk image. The computing system applies the monitored block-level operations simultaneously to other N?1 identical disk according to similar customizations written in customization scripts. After applying the block-level operations, the N identical disk images become N customized disk images. Identical Virtual Machines (VMs) operating in the N identical disk images become N customized VMs by operating based on the N customized disk images.
